Question

A figure is rotated 180°. If one of the points on the image is G'(4, -8), what were the coordinates of G?

Answer 1

When you rotate 180 degrees, you multiply the x and y values by -1. so the points of G is (-4, 8)

Answer 2

Answer:

$G = (-4,8)$

Step-by-step explanation:

Let assume that rotation is centered at origin. A rotation of 180° means that G' is the antiparallel version of G. That is:

$G' = - G$

$(4,-8) = -G$

$G = -(4,-8)$

$G = (-4,8)$
