Question

y and x have a proportional relationship, and y= - 12 when x=3what equation represents this relationship?

Answer 1

The x and y are in proportional relationship. So,

`\begin{gathered} y\propto x \\ y=kx \end{gathered}`

Here, k is constant.

Substitute -12 for y and 3 for x in the equation to determine the value of k.
