To find the equation, find the slope. To find the slope find the change in y/ change in x.
(1-6)/(-6+12)= -5/6
Then use the equation, y=mx+b, to solve for y int. First, substitute the slope in for m, and then choose a coordinate to substitute for y and x.
1=-5/6(-6)+b
1=5+b
-4=b
y=-5/6x-4 is the equation of the line.
