Question

Which equation represents a proportional relationship where the constant of proportionality is 2? * y=2+k k=2y y=2+x y=2x

Answer 1

y = 2x

Explanation:

here in this case, x = independent variable whereas y is the dependent variable.

Now, Equation that represents a proportional relationship with a constant or proportionality of 2 is y =2x.

as y= 2x

⇒ y/x = 2
