Final answer:
The point that would represent the unit rate on a graphed line is where the line intersects the vertical axis (y-axis) at zero.
Step-by-step explanation:
If you graphed a line to represent the situation, the point that would represent the unit rate would be the point where the line intersects the vertical axis (y-axis) at zero. This is because the unit rate represents the change in the dependent variable (y-axis) per 1 unit change in the independent variable (x-axis).
