#### Answer

The table represents a linear function.
The graph is attached below.
The equation for the relationship is y=11.2-$\frac{1}{17}$x
The relationship exhibited is that the initial gallons of gas is 11.2 before any miles are travelled and that for every 17 miles travelled which is independent, 1 gallon of gas i.e. the dependent variable is used and so slope is -$\frac{1}{17}$

#### Work Step by Step

a. The relationship is linear as it passes the vertical line test.
b. The equation for the relationship is y=11.2-$\frac{1}{17}$x
The slope was calculated by using (0,11.2) (17,10.2). m=$\frac{y2-y1}{x2-x1}$ = $\frac{10.2-11.2}{17-0}$ = - $\frac{1}{17}$
The y-int is 11.2 because this occurs when the independent variable is equal to 0.
