- Rectangle MNOP with vertices M(-7.-2). M(-5, -1), 0(-27), and P(-4,-8):
90° counterclockwise about the origin

M’ = (2, -7)

N’ = (1, -5)

O’ = (7, - 2)

P’ = (8,- 4)

Step-by-step explanation:

Swap the x and y coordinates and negate the y coordinate.

M(-7, -2) swap = (- - 2, -7) = (2,-7)

N(-5, - 1) swap = (- - 1, - 5) = (1, - 5)

O(-2,-7) swap = (- -7, -2) = (7, - 2)

P(-4,-8) swap = (- - 8, - 4) = (8, - 4)
