Question

Triangle ABC is graphed on the coordinate plane, as shown below.

Triangle ABC is dilated by a scale factor of 2 with
a center of dilation at the origin to create triangle
A’B’C’. What are the coordinates of the vertices
of triangle A’B’C’?

Answer 1

D. (4,4), (8,8), (-8,4)

Explanation:

We have A (2,2), B(4,4) and C (-4,2)

Dilation by factor of 2: (x,y) => (2x,2y)

A (2,2) => A'(4,4)

B(4,4) => B'(8,4)

C (-4,2) => C'(-8,4)

Answer 2

I believe the answer would be D.
