Answer:

3rd option

Step-by-step explanation:

A direct variation is expressed in this form:

y = kx

1. y - 4x = 8

y = 4x + 8 is not a direct variation

2. y + 2 = 7x

y = 7x - 2 is not a direct variation

3. y - 3x = 0

y = 3x is a direct variation

4. y = 5x - 2

y = 5x - 2 is not direct variation

Solve for y.<br> 6 y<br> 36 3<br> y=Blank 1<br> Blank 1<br> Add your answer
Gemiola [76]

Answer: 60.5

Step-by-step explanation:

Since you’re solving for y, you want to get it by itself to get a clean reading answer of y= blank.

So in 6y=363 you would want get rid of that 6 from the y, do you would divide both sides by 6.

6y/6 = 363/6

And then you’d get

y=60.5 once you finish dividing.
