Question

Jim has a membership to a comic book club. He pays $9.00 per month for membership and $2.50 for each comic book he purchases. What are the parameters in this scenario?
A.) The parameters are not defined.

B.) The slope is 9 and the y-intercept is 2.5

C.) The slope is 2.5 and the y-intercept is 9.

D.) x and f(x)

Answer 1

The answer is C) the slope is 2.50  and the y-intercept is 9, assuming the question refers to the parameters of his monthly cost.

His cost function could be described as y= 2.5x + 9, where x is the number of comic books he purchases. If he buys no comic books, he still has to pay the $9 membership fee.
