Question

Triangle PQR has the coordinates P(2,4), Q(-2,4), R(0,-5).

Write the coordinates of the vertices of the image of a triangle after a dilation of 2.

Answer 1

I hope I got this correct.

Explanation:

Multiply the coordinates by 2.

P(4,8)

Q(-4,8)

R(0,-10)

For the future if you get stuck, multiply the coordinates by the dilation number.
