Step 1.1

Rewrite.

$y - 5 = 0 + 0 - \frac{6}{7} x$

Step 1.2

Simplify by adding zeros.

$y - 5 = - \frac{6}{7} x$

Step 1.3

Combine $x$ and $\frac{6}{7}$ .

$y - 5 = - \frac{x \cdot 6}{7}$

Step 1.4

Move $6$ to the left of $x$ .

$y - 5 = - \frac{6 x}{7}$

Step 2

Add $5$ to both sides of the equation.

$y = - \frac{6 x}{7} + 5$

Step 3

The given equation $y = - \frac{6 x}{7} + 5$ can not be written as $y = k x^{2}$ , so $y$ doesn't vary directly with $x^{2}$ .

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