Answer:
The slope is +2
Explanation:
Count the squares on the grid. Rise, how many up, then the run, how many to the right for the graphed line to cross the grid lines.
Up 2, over 1. So +2
Or by the numbers of the coordinates. (0,0) (1,2)
Y values for the rise: 2-0=2 .X-values for the run 1-0=1
2 over 1. 2/1 is +2
