Answer:

Step-by-step explanation:
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

7 3/4 × 3/4 = So u add 3×3=9
Then add 4×4=16 Give you 9/16
Then you add that 7 you left out with 9/16
But just the 9 not the 16
7 × 9 = 63 And your answer is 63/16
