The distance a car drives, in miles, is proportional to the number of gallons of gas it uses. The graph shows this relationship. A line graph, titled Distance Traveled by a Car, representing the relationship between gas in gallons and distance in miles. The following points are plotted (0, 0), (1, 21,) and (5, 105). A line is drawn through the points, starting at the origin. Select from the drop-down menu to correctly complete the statement. The unit rate is ___ .

Answer:

21 miles per gallon

Step-by-step explanation:

The formula for slope is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Using the points (0, 0) and (1, 21), we have

m = (21-0)/(1-0) = 21/1 = 21

This means they get 21 miles per gallon of gas.
