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 is the slope of this line? the slope of this line is blank.

Explanation:

Step1: Recall slope formula

Slope $m = \frac{y_2 - y_1}{x_2 - x_1}$

Step2: Pick two points on line

Use $(0,0)$ and $(6,24)$

Step3: Substitute into slope formula

$m = \frac{24 - 0}{6 - 0}$

Step4: Calculate the slope

$m = \frac{24}{6} = 4$

Answer:

4
