Question

What does the y-intercept represent in the context of the problem?

the total cost at 8 visits
Total cost at 12 visits
the number of visits at $0 total cost
the total cost at 0 visits

PLEASE HELP!!!!

Answer 1

D

Explanation:

The equation of the line is y = 2x + 8

To find the y intercept we make x=0

When x=0 y=8

if y is total cost and x is number of visits then at zero visits (x=0) the total cost is 8, which is what you would find using choice D

Answer 2

• D) the total cost at 0 visits

--------------------------------

The y-intercept is (0, 8)

• The x-coordinate, number of visits ⇒ x = 0, zero visits,
• The y-coordinate, total cost ⇒ y = 8, total cost is $8.

It represents the cost with zero visits, likely the membership cost, therefore the correct choice is D.
