How do you find slope intercept from a graph

Makovka662 [10]

The slope intercept is equal to the rise/run.

So lets say to get from one point to the other, you go down 2 units and go right 3 units.

Since you went down it is a -2. If you had gone up 2 units, then it would be a positive 2.

Since you went to the right, it is a positive 3. If you had gone left 3 units, then it would be -3.

-2/3
