Question 668021
Slope = {{{(-3 - 105)/(6-(-3)) = -108/9 = -12}}}
...
Use either point and slope of -12 to solve for y intercept
105 = -12(-3) + b
105 = 36 + b
b = 105 - 36 = 69
...
Check using the other point
-3 = -12(6) + b
b = -3 + 72 = 69
....
Linear equation is
{{{highlight_green(y = -12x + 69)}}}
;;;
{{{graph(300,200,-10,10,-5,10,-12x+69)}}}

Delighted to help.
