$y = \frac{1}{4} x$ , $y = - \frac{1}{4} x$

Step 1

Combine $\frac{1}{4}$ and $x$ .

$y = \frac{x}{4}$

$y = - \frac{1}{4} x$

Step 2

Combine $x$ and $\frac{1}{4}$ .

$y = - \frac{x}{4}$

$y = \frac{x}{4}$

Step 3

Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.

$(0, 0)$
