If y varies directly with x, then y= when x = –2. What is the value of x when y= -4? A. x= 1
B. z = 2
C. x = 4
D. r = 16

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

noncoplanar points are points that do not lie on the same line.
