Answer:

m=4/3 and b=5
Step-by-step explanation:
We want to find the equation of the line passing through (3,9) and (6,13).
We determine the slope using:

Let:

We substitute the points to get:

We now use the formula:

We substitute to get:

Multiply through by 3 to get;

We expand further to get:

This implies that:

We solve for y to get:

Therefore m=4/3 and b=5
Just multiply the 12 miles by two and the gallon by 2 to get an equivalent unit rate
24 miles per 2 gallons
