Answer:
y=1/3x-2
Explanation:
If the graph is counting by one's, then all you need to do is find the rise over run to identify the slope Rise is going either up or down and run is going either left or right. Up and right is positive while down and left are negative. In this case you are going right 3 and up 1. Since we are finding the slope (m) you do 1/3 which would be your slope. To identify the y intercept (b) you find the point where the line intercepts the y intercept which is -2.
