Dee's clothing is having a discount of 40% on all shirts.
Let x represent the regular price of any shirt in the store. Enter an expression that can be used to find the sale price of any shirt in the store.

- (2, -7)

- lines r and s and lines t and u must be parallel

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)
