find the slope, if one exists, from the given points (-11,-9) and(-20,-17)
====
slope = change in y /change in x = (-17--9)/(-20--11) = -8/-9 = 8/9

If you know the coordinates of two points using the formula: m=(Y1-Y2)/(X2-X1)
Easy you can find the slope of the line that passes through these points.
In our case we have:m=%28-17-%28-9%29%29%2F%28-20-%28-11%29%29=%28-8%29%2F%28-9%29=8%2F9.
