Question

which equation shows a direct proportional relationship between two variables x and y.y= 2+xy= 2xy= 2-xy= 2/x

Answer 1

The equation which shows the direct relationship between x and y can be determined as,

`y=kx`

Where k is constant.

Thus, y=2x is the required solution which shows direct proportional relationship.

Thus, option (ii) is correct.
