A copy shop charges $0.20 per photocopy for orders of up eight copies. Which graph represents this relation?

Answer:
D
Step-by-step explanation:

This eliminates A and C
1 copy costs 20 cents
8 copies costs 1.60
The number of copies is the independent variable, so it should be plotted on the x axis
