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