The line is graphed with a slope of $\frac{1}{3}$ rather than 3.

Work Step by Step

The equation is in slope-intercept form so we can see that the slope is 3. Slope is also known as rise over run, which in this case means that each point on the graph should rise 3 units upward for every 1 unit to the right, but this line was graphed with the rise and run mixed up giving it a slope of $\frac{1}{3}$.
