Point slope is y-y1=m(x-x1) Keep y and x as they are (do not plug anything in for those). Variable m is the slope. x1 and y1 are part of the point, which is in (x, y) form. With the information given, plug each into the equation. m= 2 (It's the slope) x1=-8 y1=5 Put these variables into the equation like this- y-5=2(x--8) The two negatives cancel out (between x and 8) so your final answer is- y-5=2(x+8)
