A triangle has vertices with coordinates (2, 0), (3, -1), and (-2, -5). If the triangle is dilated by a scale factor of 3 with the origin as the center of dilation, what are the coordinates of the vertices of the image.

If the scale factor is 3, then

A(2,0) ----> A' (6,0)

B(3,-1) ---> B' (9,-3)

C(-2,-5) --> C' (-6,-15)

Can't get any simpler than that.

Might be a good idea to graph the original triangle and the new triangle.

What do you notice ?
