Question

What is the direct variation equation if k = 3?

O y=-3x
O 3 = xy
O y = 3x
O x=3y

Answer 1

Answer: x=3y is the direct variation

Answer 2

• y = 3x

Explanation:

Direct variation formula is:

• y= kx

Since k = 3, the equation becomes:

• y= 3x

Correct option is option C or third option
