Answer this please lol

Well linear equations are written in the format:

mx + b = y

So in this case our b = 0 since there is no constant in any of the answers.

if x = 7, y = 2

Plug that in:

7m = 2

And then we can divide both sides by 7

To get m = 2/7

And then we plug m in to get:

y = 2/7x

Which is D
