 Here is how I would attack this problem... We know the slope is down (from left to right), so it must be NEGATIVE p = the X horizontal r = the Y vertical In the picture, the X is bigger than the Y Slope is Y/X Plug in some numbers, any numbers Y -1 ___ ______ X 4 see below... So let’s guess that X = 4 and Y = 1 maybe -4, 1 and 4, -1 |
