I GIVE MEDALS! Thomas wants to rent a lawn mower. He has to pay a fixed base cost plus a daily rate for renting the lawn mower. The table shows the amount of money, y, in dollars, that Thomas has to pay for renting the lawn mower for x days:

Lawn Mower Rental

Number of days(x) Rent (dollars)(y)
(x) (y)
0 12
1 21
2 30
3 39
4 48

Which equation best shows the relationship between x and y?
y = x + 21
y = 9x + 21
y = 9x + 12
y = x + 12

your answer would be y=9x+12. This is because the graph tells you that when you have rented the lawn mower for 0 hours, it will cost 12 dollars, which is the fixed base. Then if you look carefully at the table, you will notice that Y will go up by 9 every time.
