Lines will not always be written initially in y=mx+b form. Sometimes you will need to do some simple
manipulation (typically one or two steps) to rearrange into this form.
Exercise #3: For each of the following equations, rearrange them into y = mx +b form and identify the slope
and y-intercept of the line.
(a) y +2x = 7
(b) 2x+3y = 12
(c) 4x -6y = 7
Answer:
a. y = -2x + 7
b. y = -⅔x + 4
c. y = ⅔x - 7/6

Which real world scenario matches this inequality? 10X < 4X +2 The cost of 10 shoes is greater than the cost of 4 shoes plus $2 socks. The cost of 10 shoes is greater than the cost of 4 shoes plus $2 socks. The cost of 10 shoes is less than the cost of 4 shoes with a $2 off coupon. The cost of 10 shoes is less than the cost of 4 shoes with a $2 off coupon. The cost of 10 shoes is less than the cost of 4 shoes with $2 socks. The cost of 10 shoes is less than the cost of 4 shoes with $2 socks. The cost of $2 is greater than the cost of 4 shoes.
Answer:
The cost of 10 shoes is less than the cost of 4 shoes with a $2 off coupon.
Explanation:
The inequality corresponds closely to the cost of 10 shoes being less than cost of 4 shoes with $2 off coupon. Closely because there is an error here the constant $2 off coupon should mean it is reducing the price of 4 shoes and therefore a minus sign should come before it, equation should be 10x<4x-2.
We can see that X is the price per shoe here

Step-by-step explanation:
Given problem;
Write the equation of the line with the given slope and y-intercept
The equation of a line is expressed as;
y = mx + b;
m is the slope and b is the y-intercept
7. m = -5, b = -6
y = mx + b
Input the parameters:
y = -5x -6
8. m = 1, b = -4
y = mx + b
Input the parameters:
y = x - 4
9. m = 0.4, b = -9
y = mx + b
Input the parameters:
y = 0.4x - 9
10. m = 0, b = 3
y = mx + b
Input the parameters:
y = 3

The price of dinner was $24.80. The sales tax was 8%. The server was given a 15% tip (calculated after tax was added). What was the total cost of the meal?
A
$5.70
B
$25.03
C
$30.50
D
$30.80
Answer:
D. $30.80
Step-by-step explanation:
8/100=0.08
0.08*24.80=1.984
1.984+24.80=26.78
15/100=0.15
0.15*26.78=4.017
4.017+26.78=30.80
Ben and Ella are filling goodie bags for a party. Each goodie bag needs an eraser, a bubble wand, and a few candy bar bites. Ben filled 25 goodie bags in 20 minutes. Ella filled 27 goodie bags in 24 minutes. Who filled goodie bags at a faster pace?
Answer:
Ben
Step-by-step explanation:
25 goodies = 20 minutes
27 goodies = 24 minutes
Let's use ratio, divide both of them by their minute
25/20 = 20/20
27/24 = 24/24
1.25 goodies = 1 minute
1.12 goodies = 1 minute
1.25 is bigger than 1.12.

Step-by-step explanation: Think back to your elementary days: how did you learn to round numbers? Chances are, your teacher taught the class how to round up or down from the number 5. In other words, if the last number is below five, you might round it down, and if it’s above, it gets rounded up.
In fact, there are a whole plethora of rounding rhymes that can easily be found on the internet. Complete a quick Google search, and you might find something like, “5 and above, give it a shove! 4 and below, let it go!”. While these sayings might seem like a great solution to help kids quickly learn to solve problems, how do children know what place value they are rounding to?
kids with scores
Before the current Common Core or individual state standards were established, mathematics was often taught by encouraging students to memorize facts and learn tricks to complete problems. Rounding is no exception, as many educators have encouraged kids to use rhymes like those described above. Needless to say, it doesn’t teach a child the underlying concept itself.
Below we’ll explore exactly why teaching math tricks don’t work, even if it helps students to arrive at a correct answer. Then, keep reading to discover 7 of the best ways to teach rounding numbers.
Why Getting Answers Correct is Not Enough
As mentioned above, teaching kids tricks or “hacks” to complete math problems can sometimes be helpful, it doesn’t help your child understand the mathematical concept behind the skill. For kids, teaching them to think about the number 5 and round up or down can help them arrive at the right answer, but they aren’t thinking about place value when they use the trick. So, if children are completing a rounding activity, they don’t know if they should round to the nearest ten or hundred. In fact, they might not know why they’re rounding up or down at all!

Write the equation of the line through the points (4, 5) and (12, 9)
Answer:
y = 1/2x + 3
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 5 / 12 - 4 = 4/8 = 1/2
y = mx+b
slope/m = 1/2
y = 1/2x + b
5 = 1/2(4) + b
5 = 2 + b
3 = b
y = 1/2x + 3
The equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6
From the question,
We are to determine the equation of the line passing through the points (4, 5) and (12, 9)
Using the formula,
[tex]\frac{y-y_{1} }{x-x_{1}} = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
From the given information
x₁ = 4
y₁ = 5
x₂ = 12
y₂ = 9
Putting the parameters into the formula, we get
[tex]\frac{y-5}{x-4} =\frac{9-5}{12-4}[/tex]
Then,
[tex]\frac{y-5}{x-4} =\frac{4}{8}[/tex]
[tex]\frac{y-5}{x-4} =\frac{1}{2}[/tex]
Then,
[tex]x - 4 = 2(y-5)[/tex]
[tex]x - 4 = 2y-10[/tex]
[tex]x -2y = -10 + 4[/tex]
[tex]x -2y = -6[/tex]
Hence, the equation of the line passing through the points (4, 5) and (12, 9) is x - 2y = -6

Gail Martinez is employed at My Best Books. She has family medical coverage through the group medical plan that My Best Books provides for its employees. The annual cost of Martinez's family membership is $3,900. The company pays 50% of the cost. How much does she pay annually for medical insurance? *
Answer:
$1850
Step-by-step explanation:
The annual cost of Martinez's family membership for medical insurance is $3,900.
The company pays 50% of the cost.
So, the cost paid by the company= 50% of $3,900.
[tex]=\frac {50}{100}\times 3900=\$1850[/tex]
The remaining cost for the family medical insurance must be paid by Gail Martinez.
So, the annual payment by her =$3900-$1850=$1850
Hence, she pays $1850 annually for medical insurance.

Slope of dotted lines: 1
Slope of reflection line: -1
Step-by-step explanation:
For the dotted lines, the rise up by one unit and run for one unit, thus their slopes are 1.
For the reflection line, it does the same thing as the dotted line, but instead of rising one unit, it goes down for one unit and runs for one unit, making its slope -1.
