Answer:

8.) M' (-1, -5), D' (1, -5), A' (4, -3), and W' (-1, -4)

9.) H' (2, 3), L' (0, 2), P' (3, -2), and Q' (2, 1)

10.) S' (4, -4), T' (5, -5), J' (4, -4), and A' (3, -3)

11.) W' (1, 3), S' (1, 1), P' (1, -2), and I' (1, -1)

Explanation:

8.) The original coordinates are: M (-1, 5), D (1, 5), A (4, 3), and W (-1, 4). We are reflecting these coordinates over the x-axis. This means the x-coordinates stay the same and the y-coordinates flip to the opposite sign. The coordinates become: M' (-1, -5), D' (1, -5), A' (4, -3), and W' (-1, -4).

9.) The original coordinates are: H (-2, 3), L (0, 2), P (-3, -2), and Q (-2, 1). We are reflecting these coordinates over the y-axis. This means the y-coordinates stay the same and the x-coordinates flip to the opposite sign. The coordinates become: H' (2, 3), L' (0, 2), P' (3, -2), and Q' (2, 1).

10.) The original coordinates are: S (4, 2), T (5, -2), J (4, -3), and A (3, -1). We are changing the y-coordinates to -x. This means the x-coordinates stay the same and the y-coordinates become the negative of the x-coordinates. The coordinates become: S' (4, -4), T' (5, -5), J' (4, -4), and A' (3, -3).

11.) The original coordinates are: W (-2, 3), S (-2, 1), P (-4, -2), and I (-5, -1). We are changing the coordinates of x to 1. This means the y-coordinates stay the same and the x-coordinates all become 1. The coordinates become: W' (1, 3), S' (1, 1), P' (1, -2), and I' (1, -1).

Hope this helps,

A.W.E.S.W.A.N.
