The system of equations are $\"\"$ and $\"\"$ .

The slope-intercept form of line equation is $\"\"$ .

Rewrite the equations in standard form.

Case (i):

$\"\"$ (Original equation)

$\"\"$ (Subtract $\"\"$ from each side)

$\"\"$ (Apply additive inverse property: $\"\"$ )

Case (ii):

$\"\"$ (Original equation)

$\"\"$ (Add $\"\"$ to each side)

$\"\"$ (Apply additive inverse property: $\"\"$ )

$\"\"$ (Multiply each side by negative one)

$\"\"$

Make a table to find a solution that satisfies both equations.

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

Observe the table:

The solutions are equal at $\"\"$ .

Hence, the solution set is $\"\"$ .
