Question

The cost to belong to a gym is $25 each month and a one time fee of $100 to join.

What is the slope and the y-intercept in this situation.

a)
The slope is the the one time fee to join. The y-intercept is the cost of the gym each month.

b) The slope is the cost of the gym each month. The y-intercept is the one time fee to join.

c) The slope is the one time fee to join. The y-intercept can not be determine in this problem.

d) The slope can not be determined in this problem. The y-intercept is the one time fee to join.

Answer 1

C(m)=25m+100 and this is the slope-intercept form of a line y=mx+b, where m is the slope and b is the y-intercept.

In this case the slope is 25 and the y-intercept is 100.
