Find the slope

2/3
-2/3
3/2
-3/2

It’s 3/2 you can look at the the point (0,1) and (2,4) you can use a method called rise over run you got up 3 over 2 units to get to the next point

The slope is 3/2.

Method:

Look at two perfect points like (-2,-2) and (0,1)
Then use rise/run triangle to find the slope in the quickest way.
Start from point (-2,-2), move 3 units up and 2 units to the right to reach point (0,1).
