Question

Tell whether x and y are proportional. If so, find the constant of proportionality. x - y=0

Answer 1

Simplify the equation x-y=0.

`\begin{gathered} x-y=0 \\ x=y \\ x=(1)y \end{gathered}`

The general equation for proportional relationship is,

`y=kx`

Where, k is constant of proportionality.

So equation y=(1)x is a proportional relation, with k=1.

So correct answer is,

x and y are proportional with k=1.
