Answer:
y = 12x + 10
Step-by-step explanation:
Since there is a flat fee you make that your y intercept because that is when x is zero, and x represents hours, so for 0 hours you are at 10 dollars. y = 12(0) + 10. It's 12x because for every hour, x, you pay 12 dollars. 12 dollars times the number of hours x. y = 12x + 10
