2. Consider the line segment below. B

M

(7x+8) cm

(9x - 8 cm

a. If AB is 128 centimeters long, what is xe

b. What is the length of AM

c. What is the length of BMS

d. Is point M the midpoint of AB Justify your answer.

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)
