m=%28y%5B1%5D-y%5B2%5D%29%2F%28x%5B1%5D-x%5B2%5D%29 where (-8, 6.5) and (9, -11)
m=%28%286.5%29-%28-11%29%29%2F%28%28-8%29-%289%29%29
m=-%2817.5%2F17%29=-%2835%2F34%29=-1%281%2F34%29=-1.0294117647058823529411764705882
y=mx%2Bb
%28-11%29=%28-%2817.5%29%2F%2817%29%29%28-8%29%2Bb
-11=%28140%2F17%29%2Bb
b=-%28327%2F17%29=19%284%2F7%29=19.235294117647058823529411764706
