What do I do when rotating a figure 90, 180, and 270 degrees?
What are
90: Flip x and y value. In new coordinate negate the x value.
180: Negate both x and y.
270: Flip x and y value. In new coordinate negate the y value.

A triangle has vertices A(−1,0), B(1,2), and C(8,-4). Reflect the triangle over the y-axis and then dilate it by a scale factor of 2 about the origin. What are the new coordinates of the vertices?
What is
Reflect: A:(1, 0) B:(-1, 2) C:(-8, -4)
Dilate by 2: A:(2*1, 2*0) B:(2*-1, 2*2) C:(2*-8, 2*-4)
Solution: A':(2, 0) B':(-2, 4) C':(-16, -8)

How does reflecting over the line y=-x differ from rotating by 180 degrees?
What is
When reflecting over the line y=-x you need to flip x and y then negate both.
When rotating by 180 degrees you only negate x and y.
