If y varies directly with x, find the value of y when x = 27 for the direct variation with the given information. y = 7 when x = -9 y =​

Given:

y varies directly with x,

It is given that y = 7 when x = -9.

To find:

The value of y when x = 27 for the direct variation.

Solution:

It is given that y varies directly with x, so

            ...(i)

Where, k is the constant of proportionality.

It is given that y = 7 when x = -9. Putting these values in (i), we get

Putting in (i), we get

Putting ,  we get

Therefore, the required value is .
