What is (87.5y + 12.2x) – (54.3y + 13.9x), simplified?

(87.5y + 12.2x) – (54.3y + 13.9x)

First distribute the - to the (54.3y + 13.9x).
Now you have 87.5y + 12.2x - 54.3y - 13.9x.

Combine like-terms.

33.2y - 1.7x is the answer simplified.

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
