Answer:
rotation of 180 degrees, and then dilation by ⅓
Step-by-step explanation:
Given
See attachment for triangles
Required
The transformation from ABC to A"B"C
Taking points A and A" as points of references.
We have:
A = (-9,3)
A" = (3,-1)
First, A is rotated by 180°.
The rule is:
(x,y) => (-x,-y)
So:
A = (-9,3) ==> A'(9,-3)
Next is a dilation by ⅓.
So:
A" = ⅓ * A
A" = ⅓ * (9,-3)
A" = (3,-1).
