I will explain in the comment

Answer: C.) y=9x+12


Step-by-step explanation:

From the given table we can see in 0 days the rent of lawn mower =$12

Let's check all the given options

A) y=x+21

At x=0, y=21

It is not the required equation.

B) y=9x+21

At x=0, y=21

It is not the required equation.

C) y=9x+12

At x=0, [tex]y=12[/tex]

At x=1, [tex]y=9(1)+12=9+12=21[/tex]

Atx=2,[tex]y=9(2)+12=18+12=30[/tex]

It is the required equation which shows the best relationship between x and y.
