Question

Is 3y=13x a direct variation, then if so, how do you find y when x=4?

Answer 1

Answer:

Step-by-step explanation:

Where an equation can be written as

y=m⋅x for a constant m then it is a direct variation

Therefore,

3y=1/3x can be written as y=(1/9)x.

Hence, it is a direct variation.

When x=4

y=(1/9)(4)=4/9

Y=4/9
