Question

at a gas station, the price of gas is 4 dollars per gallon. the graph below represents the relationship between the cost of gas and the number of gallons of gas purchased. what does the slope mean in this situation? slope = \\(\frac{vertical\\ distance}{horizontal\\ distance}\\) = 4 options: each additional gallon adds $4 to the total cost. 4 gallons cost 1 dollar.

Explanation:

The slope of the graph represents the rate of change of total cost (y-axis) with respect to the number of gallons (x-axis). A slope of 4 means for each 1-unit increase in gallons (horizontal change), the total cost increases by 4 units (vertical change), which matches the given price of $4 per gallon. The second option incorrectly reverses the relationship between cost and gallons.

Answer:

Each additional gallon adds $4 to the total cost.
