To determine the unit rate, we need to know the slope of the line on the graph. The unit rate represents the number of miles driven per gallon of gas used.
In this case, without specific values or a visual of the graph, let's use logical assumptions based on the options provided:
- If the graph indicates that for every gallon of gas the car can travel 1 mile, the unit rate is 1 mile per gallon.
- If it's indicated that for every gallon, the car drives 5 miles, then the unit rate would be 5 miles per gallon.
- If the graph shows the car can cover 21 miles per gallon, then the unit rate is 21 miles per gallon.
- If it covers 105 miles per gallon, then the unit rate is 105 miles per gallon.
To select the correct unit rate, find the value of miles per gallon indicated in your graph's data.
If we assume that the correct answer based on typical distances and efficiency might be 21 miles per gallon, but please verify against the graph you have for accuracy.
So, the unit rate is 21 miles per gallon if that's what is represented in the graph.
