A y=2x B y=3x C y= 2x+1 D y=3x+3

A) y=2 x

Step-by-step explanation:

Explanation:-

  we will choose equation y =2 x

given data

x  :   5        8     9       11

y   :    10     16    18      22

substitute x =5 ⇒ y = 2(5) =10

substitute x =8 ⇒ y = 2(8) =16

substitute x =9 ⇒ y = 2(9) =18

substitute x =11 ⇒ y = 2(11) = 22

The data is satisfied the equation y =2 x

The relationship of two variables of  the equation is y =2 x
