$y - 2 x - 8 = 0$

Step 1

Move all terms not containing $y$ to the right side of the equation.

Tap for more steps...

Step 1.1

Add $2 x$ to both sides of the equation.

$y - 8 = 2 x$

Step 1.2

Add $8$ to both sides of the equation.

$y = 2 x + 8$

Step 2

The given equation $y = 2 x + 8$ can not be written as $y = k x^{2}$ , so $y$ doesn't vary directly with $x^{2}$ .

$y$ doesn't vary directly with $x$
