Question

The values of x and y vary directly and one pair of values are given write an equation that relates x and y X=2 y=5

Answer 1

Given:

The values of x = 2 and y = 5

The relation between the values of x and y:

`y=(?)/(\square)\text{x}`

Now we need to have y = 5 for x = 2 so let us substitute 5/2 in place of blank space.That is,

`y=(5)/(2)x`
`\begin{gathered} y=(5)/(2)x \\ 5=(5)/(2)*2 \\ 5=5 \end{gathered}`

Hence, the relation gets satisfied.

Hence, the relation is :

`y=(5)/(2)x`
