Answer: The slope is 3.
Step-by-step explanation: The line crosses the grid at (-1,-1), (0,2) and (1,5)
Subtract the y-values to find the rise. 5-2=3 . 2-(-1)=3
The rise is 3.
Subtract the x-values to find the run. 1-0=1 0-(-1)=1
The run is 1
rise/run is the slope
3/1 is the slope.
We usually leave out the denominator if it is 1.
