Answer:
y=1/3x+5
Explanation:
1/3 tells us the slope of the line. it tells us how many units up (in this case 1) and how many across (here it was 3). so the rise/run was 1/3. As for the 5, this tells us where the line crosses the y-axis. You can see that at the point (0,5) the line crosses, so 5 would be the y-intercept.
I hope this helps :)
