Question

Im trying to figure out a equation that relates to x and y y=20 x=12

Answer 1

We have been told from the question that the relationship between y and x is a direct variation.

x varies directly with y

then the relationship will be

y= k x

where k is a constant

so we can obtain k since the values of x and y have been given

k = y/x

y = 20, x = 12

k = 20/12

k= 5/3

`\begin{gathered} y\text{ = kx} \\ y\text{ = }(5)/(3)x \end{gathered}`

The relationship is 5/3x
