Sea water contains __________.
Suppose a line segment whose endpoints are T(x1,y1) and U(x2,y2) is reflected over y=x to create T′U′− . The coordinates of the image are T′(−4, 3) and U'(1, 7) . What are the values of x1 , x2 , y1 , and y2 ?
Answer:
T'(3, -4) U'(7, 1)
Explanation:
(x, y) ---> (y, x)
T'(y1, x1) = (-4, 3) ----> T(3, -4)
U'(x2, y2)= (1, 7) -------> U(7,1)
