u need to use the point slope form to find the slope then use the slope intercept formula to find the intercept, then u will have the equation.
m=%28%28y-y%29%2F%28x-x%29%29 (-4,4)(8,8) substitute
m=%28%284-8%29%2F%28-4-8%29%29 subtract/add
m=%28%28-4%29%2F%28-12%29%29 reduce
m=%281%2F3%29
_____
y=mx%2Bb
8=%281%2F3%298%2Bb multiply
8=%288%2F3%29%2Bb subtract
8-%288%2F3%29=b make subtractable fraction
%2824%2F3%29-%288%2F3%29=b subtract
%2816%2F3%29=b
____
y=%281%2F3%29x%2B%2816%2F3%29
this is the equation for the line that passes through those points.
