Graph






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
