This is how to find a slope:
y2 - y1 over like a fraction on
x2 - x1
So we would do
-2 - 1 over
0 - 2
and you would get the slope of
-3/-2
Since there can't be two negatives it turns into a positive fraction like this
3/2 = Slope
If you want to graph this it would rise 3 points in the y axis and run 2 points in the x axis
