To determine the point on the graph that represents the unit rate, we need to identify the rate of change between the total earnings, $y$, and the number of hours worked, $x$.

The unit rate is the earnings per hour, which corresponds to the change in $y$ when $x = 1$.

Looking at the answer choices and the graph:

• (1, 30): This indicates that when $x = 1$ hour, $y = 30$ dollars. This represents the amount earned per hour, which is the unit rate.
• Other points:
  • (0, 0): This is the starting point (no hours worked, no earnings).
  • (30, 1): This is likely a misrepresentation as it implies 1 dollar for 30 hours.
  • (4, 120): This shows that 4 hours of work results in 120 dollars, but it does not represent the unit rate.

Therefore, the point (1, 30) represents the unit rate of earnings per hour.

Tip: The unit rate can always be identified by finding how much of the dependent variable (y) changes when the independent variable (x) is increased by 1.
