Question

Which best represents the relationship between x and y

y=2x
y=x+2
y=4x
y=x+4
​

Answer 1

two variables in which the value of one of them (usually y) depends on the value of the other one (usually x)

Answer 2

In y = 2x the value of y is twice the value of x, and in y = x + 2 the value of y is two more than the value of x.

Same for the y=4x and y=x+4, just plug the numbers into the sentence.
