Triangle CAT is located at C (-5, 2), A (-4, 4), T (-1, 2).  Find the coordinates of its image after a dilation with a scale factor of 4

Answer 1

Dilation about the origin multiplies every coordinate by the scale factor.

C' = 4(-5, 2) = (-20, 8)

A' = 4(-4, 4) = (-16, 16)

T' = 4(-1, 2) = (-4, 8)
