Solve. Assume the exercise describes a linear relationship. When writing a linear equation, write the equation in
slope-intercept form.
-A gas station sells 4820 gallons of regular unleaded gasoline on a day when they charge $1.35 per gallon, whereas they sell 3850 gallons on a day that they charge $1.40 per gallon. Find a linear equation that relates
Gallons sold to price.
A)y = -19,400x + 31,026
B)y = -19,400x + 31,010
C)y = -19,400x + 30,988.2
D)y = -19,400x + 30,993.8

Question

Quizplus · Accepted Answer

The slope is calculated as (3850 - 4820) / (1.40 - 1.35) = -19,400. Using the point (1.35, 4820), the equation is y = -19,400x + 31,010.
