Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).
The only thing that you need to do is Divide -2 on both sides to isolate the M. so 7/-2 M=3.5
[(51 + 3) - 3^2]/9 * 2
[ 54 - 3^2] / 9 * 2
[ 54 - 9 ] / 9 * 2
[45] / 9 * 2
5 * 2 = 10
