a.) - 2
b.) - 1/2
c.) 1/2
d.) 2

b.) - 1/2

Step-by-step explanation:

The common ratio is found by taking the second term and dividing by the first term

-1/4÷ 1/2

Copy dot flip

-1/4 * 2/1

-1/2

i dont know men

step-by-step explanation:

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)
