    So for every 3 you go forwards in X, Y drops by 5. Easiest way is to find the equation, imho. So -3/5x + z=Y z = unknown so we have 1 pt to use (P). so -3/5 x 1 (our x)= -3/5 but the Y value is 4, so the difference is 4 - (-3/5) = 4.6 so the equation is -3/5x + 4.6 = Y so if Y=1 for the second pt, Q, plug it into the equation to get 1= -3/5x + 4.6 rearrange to get -3.6=-3/5x divide both sides by -3/5 x=6
