Let's call -1 as x_1 and -5 as y_1
also, 4 as x_2 and 5 as y_2
The equation of line is :

<em>Let's plug the points and get the equation of the line:</em>

Now, to find a, we substitute a in x and 1 in y of the equation of the line we just got:

Answer: 15 miles per gallon
Step-by-step explanation:
135 divided by 9
7 1/4 - 2 4/5
