Question

triangle abc is graphed on a 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 verticles 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

The answer is D, i took the test and made a 100
