Question

The equation below can be used to model the approximate cost of different numbers of carnival passes.

Cost = 10 + 8p

Which of the following is true?


A. The slope is 8 and represents the cost of eight passes.

B. The slope is 10 and represents the cost of 10 passes.

C. The slope is 8 and represents the change in cost for each additional pass.

D. The slope is 10 and represents the change in cost for each additional pass.

Answer 1

Slope-Intercept form is in the format of y=mx+b, where m is the slope and b is the y-intercept. Therefore, we can rewrite the given equation dollarsas Cost=8p+10.

We can eliminate B and D because they mention that 10 is the slope, when the true slope is 8.

A.) is the correct answer because each pass is equal to 8 dollars (dollars is an assumed unit, it could be anything though).
