Question

at a gas station, the price of gas is 3 dollars per gallon. the graph below represents the relationship between the cost of gas and the number of gallons of gas purchased. the vertical intercept is 0. the vertical intercept, 0, means that gallons cost dollars.

Explanation:

Step1: Understand the vertical intercept concept

The vertical intercept of a graph in a cost - quantity relationship (where \(y\) - axis is cost and \(x\) - axis is quantity) occurs when \(x = 0\).

Step2: Analyze the meaning for gas purchase

When \(x=0\) (number of gallons of gas purchased), the cost \(y\) (total cost in dollars) is also \(0\).

Answer:

\(0\) gallons cost \(0\) dollars.
