Which equation models a line that passes through point (-2,2) And has a slope of -8

trasher [3.6K]

So we will be using $y=mx+b$ form, in which m = slope and b = y-intercept. Since we know the slope (-8), all we need to do is solve for the y-intercept. We can do this by inserting (-2,2) into the equation and solve for b.
