Problem 3. Ryan and four of his friends were going to the movies. The movie tickets cost $8 each, they bought two popcorns at $5.75, four drinks at $2.25, and two boxes of candy for $1.75. How much money did
they spend total?

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)
