How do I make an equation and solve and graph?

Question

An automaker makes a car that can travel 40 mi on its charged battery before it begins yo use gas.Then the car travels 50 mi per gallon of gas used.Represent the relationship between the amount if gas used and the distance traveled using a table, an equation, and a graph. Is total distance traveled a function of the amount of gas used? What are the indepentent and dependent variables? Explain

Answer 1

y = (50)x + 40

Dependent variable is y, the distance the car can travel

Independent variable is x, the number of gallons of gas

To make a table, plug in values for x and y and then put them into a table.

Graph using the point coordinates you found.
