Question

I need help solving this, and finding the exact points to plot.

Answer 1

Answer:

Explanation:

Here, we want to get the equation that relates G to D

From the given question,

G represents what is left in the tank

D represents the total distance traveled

Initially, she has 18 gallons, this drops at the rate of 1 gallon per 35 miles

The equation of a straight line is:

$y\text{ = mx + b}$

where m is the slope and b is the y-intercept

Thus, we have it that:

$G\text{ = 35D - 18}$

Now, we proceed to plot the graph of the function:

For the points to plot:

when D = 20, g will be
