Answer:
4
Step-by-step explanation:
We are asked to find a slope whilst given a graph.
To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.
So based on what I see, I can see (1, 1) and (2, 5).
The rise over run is as followed :

2 and 1 meaning the first and second number within the coordinate, so substitute :


Divide :

4 is our slope.
