After filling the ketchup dispenser at the snack bar where she​ works, Kelley measures the level of ketchup during the day at different hourly intervals.

Complete parts a to c.

Question content area bottom

Part 1

a. Assuming the ketchup is used at a constant​ rate, write a linear equation that can be used to determine the level of ketchup in the dispenser after x hours. Let y represent the level of ketchup in inches.


y equals negative five eighths x plus 15

​(Type an​ equation.)

Part 2

b. How can the equation from part a be used to find the level of ketchup when the dispenser is​ full?

A.

Identify the slope of the line represented by the equation.

B.

Find the difference between the slope and the​ y-intercept of the line represented by the equation.

C.

Substitute 0 for x in the equation and solve for y.​ Equivalently, find the​ y-intercept.

D.

Substitute 0 for y in the equation and solve for x.​ Equivalently, find the​ x-intercept.

Part 3

c. If Kelley fills the ketchup dispenser just before the snack bar opens and the snack bar is open for 18​ hours, will the dispenser need to be refilled before closing​ time? Explain.

If the ketchup is used at a constant​ rate, then the equation from part a indicates the dispenser will become empty


enter your response here hours after the snack bar opens. This means that the dispenser



will become empty before closing time,

will become empty exactly at closing time,

still has ketchup in it at closing time,

and so it



will not

will

need to be refilled before closing time.
