Question

Which of the following equations is an example of direct variation between variables x and y?A. y= x/9B. y= 9/xC. y= 9xD. y= x+9

Answer 1

Given:

We have equations in options.

Required:

Which of the following equations is an example of direct variation between variable x and y.

Step-by-step explanation:

The formula for direct variation is y = kx, where k is the constant of variation.

We have

`y=(1)/(9)x\text{ and }y=9x\text{ is in form of direct variation.}`

Answer:

Option A and C is correct.
