Question

Quadrilateral ABCD has vertices A(-2,0) B(-3,-3) C(-5,-2) D(-5,2). Which of the following are the coordinates of A' after a dilation centered at the origin with a scale factor of 2 1/2?

Answer 1

A' = (-5, 0)

"A" MAY NOT BE THE ANSWER CHOICE "A" IS THE NAME OF THE POINT

Explanation:

If A = (-2,0)

Then multiplying each coordinate by 2.5 (-2*2.5, 0*2.5)

Gets us (-5, 0)
