Slope intercept form is y=m(x)+b M is the slope to find it you do the first y value minus the second y value and do the same for x -6-2. 3+1 You then divide the subtracted y values by the subtracted x values -8/4 M=-2 To find the b you plug in one set of the coordinates -6=-2(3)+b -6=-6+b b=0 So the equation is Y=-2x
