Direct variation:

We are given that x and y are directly proportional.

Recall that the standard form of the directly proportional relationship is given by

Where k is the constant of proportionality.

Comparing the standard form with the given equation we see that k is equal to 1.

$y=1\cdot x$

Let us substitute the value of x into the above equation

$y=1\cdot36=36$

Therefore, the value of y is 36.

(when the constant of proportionality (k) is 1 then the x and y values are equal)
