Triangle coordinates, dilation, rotation

Question

Daughters homework, I'm struggling to help her.

Question: Given A (4,5). What are the coordinates of A' under the composition D2 o R180 (The 2 in D2 shows like a small 2 lower than the D, same for the 180 with the R).

Answer 1

(4, 5)

(8, 10) dilated by a fact or 2

(-8, -10) rotated 180°

Helpful to plot and label.
