Question 1094151
Assign ANY other point you want along with (-2,0) so that the slope is negative.


An example  (and just one of infinite examples) is  (0,-1) with (-2,0); or another example can be  (5,-2) with  (-2,0).  You can find the equation for the line of either pair of points.


That only explains how to pick a useful point.  You can do the rest of finding the corresponding equation.
