Question

What is the image of -2, 9 after a dilation by a scale factor of 5 centered at the origin?

Answer 1

(-10, 45)

Explanation:

When dilation is centered at the origin, the coordinates of the image points are the coordinates of the original points multiplied by the scale factor.

A = (-2, 9)

A' = 5(-2, 9) = (-10, 45) . . . . image of point A after dilation
