Question

If the point (3,8) was rotated by 180 degrees about the origin its image coordinates would be

Answer 1

(-3, -8)

Explanation:

When we rotate a point 180 degrees around the origin, its ordered pair changes from (x, y) to (-x, -y). So all we have to do to figure out the point's coordinates after being rotated 180 degrees is to make both the x- and y-coordinates negative.

That gives us (-(3), -(8)) or (-3, -8). Hopefully that makes sense! :)
