Write an equation in slope intercept form for the graph of the line.​

Answers

Answer:

y = 2x - 3

Step-by-step explanation:

Slope intercept form:

y = mx + b, where m - slope, b - y-intercept

Take two points from the graph:

(2, 1) and (3, 3)

Find the slope:

m = (3 - 1)/(3 - 1) = 2/1 = 2

Find the y-intercept using point (2, 1) and the equation above:

1 = 2*2 + bb = 1 - 4b = -3

The line is:

y = 2x - 3

Answer:

Y = 2x - 3 or Y = 8/3x - 3

Step-by-step explanation:

Y = mx + b

we have a y intercept of -3 since the graph crosses the y axis only at -3 and it heads to y = 3 starting from the y intercept.

and thus we are 5 units away from 3 which is m = a/c = 8/3

m = 8/3

y = 8/3x - 3

it's either this or we'll simply plot the final and initial positions of x and y respectiveky. so m = 3-1/3-2 = 2/1 = 2

and so the equation would turn out to be -

y = 2x -3

A = 192

Step-by-step explanation:

r = 16/2 = 8

A = 3x(8)^2

8^2 = 64

A = 3 x 64 = 192

Radius is half the diameter.

The diameter is shown as 16, so the radius would be 16/2 = 8 in.

Area = 3 x 8^2

Area = 3 x 64

Area = 192 square inches

I've attached a graph to show why these two are true. Remember that in an absolute value function, the result is always positive. However, because there's a negative constant multiplying the absolute value function, this flips the graph over the x-axis and the result is now always negative. In other words, no matter how big or small x is, y will always get smaller.
