Question

Given R180(x, y) = (–x, –y) and Q (2, –5), what is R180(Q)?

Answer 1

plug in the given values

R180(x, y) = (–x, –y)

R180(2, y) = (–(2), –y) ... replace x with 2

R180(2, y) = (–2, –y)

R180(2, -5) = (–2, –(-5)) ... replace y with -5

R180(2, -5) = (–2, 5)

and that's all there is to it

Answer 2
