Question

Match the correct equation with the proportional relationship. X 1 2 3Y 1.5 3 4.5

Answer 1

First, we use the formula below.

`y=kx`

Then, we replace the point (1, 1.5) and solve for k.

`\begin{gathered} 1.5=k\cdot x \\ k=1.5 \end{gathered}`

Now, we replace it in the formula. Therefore, the equation for the given table is

`y=1.5x`
