7th grade math proportion equation? ? anyone

The answer is B.

I need 20 character for this answer

Hey there!

In this problem, we're looking for x's relation to y. We want to know what we multiply, divide, or do any other operation to on x to get y.

And that, is why we have algebra.

We take our x value, and we put a variable, z, after it. That allows us to solve for z and see what we are doing to x to get y.

Let's try one:

We have 2, and when it goes through our function, we get 16. We have:

2z = 16
z = 8

Next one:

3z = 24
z = 8

Finally:

4z = 32
z = 8

We see a common pattern. Y is just x multiplied by 8.

Therefore, your answer is B, y = 8x

Hope this helps!

Two because two of one thing is two.
