So if you know how to find slope this is a pretty easy question to solve.
Sooo,
to solve you would 2 pairs of #'s off the graph and subtract theM
Like so;
I will use the point (2,6) and (3,9).
To subtract you are going to flip the values and subtract.
9-6=3
3-2=1
This was going to represented by a fraction but since 3/1=3 the slope is just going to be 3.
