(x). (y)
0. 12
1. 21
2. 30
3. 39
4. 48

which equation best shows the relationship between x and y?

a.) y=x+21
b.) y=9x+21
c.) y=9x+12
d.) y=x+21

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,

At x=1,

Atx=2,

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

it has the same slope and a different y-intercept

hope this : )
