Answer:
Step-by-step explanation:
What is the rate in miles per gallon:
gallons used: 28 39 42
miles; 628.4 947.7 1020.6
The answer is below
Solution:
A linear function is a function in the form:
y = mx + b; where y is a dependent variable, x is an independent variable, m is the rate of change of y with respect to x, and b is the initial value of y when x is zero.
From the table, we are given the gallon used to cover a distance in miles. To calculate the rate, we can select two points from the table. Using the points in the form (miles, gallons used): (628.4, 28) and (1020.6, 42) we get:
[tex]m=\frac{1020.6-628.4}{42-28}\\\\m=28\ miles\ per\ gallon[/tex]
