For this one use the slope formula, (y2-y1)/x2-x1)
Just to have them in one place, here are the ordered pairs
(-1,-2) (2,2)
You can do these in any order, here is how I did the problem:
(2--2)/2--1)
Your y intercepts are 2 and -2
The x are 2 and -1
Now reduce. Since you are subtracting a negative, it turns into a positive.
(2+2)/(2+1)
4/3
There is our slope: rise 4 run 3 or as a fraction 4/3.
Hope this helps!
