A(−5,3),B(−2,3),C(−2,1),D(−5,1) Reflect in the y-axis. Then dilate with respect to the origin using a scale factor of 2.

Question

I need help im struggling

Answer 1

plot A, B, C, and D and connect the points

when you reflect over the y-axis, the y-values stay the same and the x-values become their opposites

A(-5,3) becomes A'(5,3)

B(-2,3) becomes B'(2,3)

C(-2,1) becomes C'(2,1)

D(-5,1) becomes D'(5,1)

plot A', B', C', and D' and connect the points

 

I hit the answer key by mistake so the rest of the solution might look like run-on sentences. dilating by a scale factor of 2 enlarges the size of the image multiply the coordinates of each point by 2 A'(5,3) becomes A"(10,6) B'(2,3) becomes B"(4,6) C'(2,1) becomes C"(4,2) D'(5,1) becomes C"(10,2) plot these points and connect the points and this rectangle is the answer
