Let
x ----> the number of minutes
y ----> the amount of fuel in gallons
we know that
The linear equation in slope intercept form is equal to
where
m is the unit rate or slope
b is the y-intercept or initial value
we have that
The unit rate or slope is equal to
----> initial value (value of y when the value of x is equal to zero)
substitute
