Question

The following points are vertices for triangle ABC: A = (3,7), B = (-1,4), and C = (6,0). What would the coordinates of triangle A'B'C' be if triangle ABC was dilated by 3.

Answer 1

To dilate a figure, the coordinates of its points must be multiplied by the dilation factor (k)

Symbolically:

Original point → Dilated point

(x, y) → (x*k,y*k)
