Answer:
y = 22x + 10 is the flat equation, but to find hours, 98 = 22x + 10 (You can rent for 4 hours)
Step-by-step explanation:
All you need to look at is what the cost is increasing/decreasing by, that is the slope. The base fee is 10 dollars. The base fee is always going to be the y-intercept. Since you have 98 dollars, make the equation equal to 98. 98 = 22x + 10, that solves down to x = 4, so you can rent for 4 hours.
