The linear function is x = y.

Rewrite the equation in standard form Ax + By = C.

x = y                       (Simplify)

Apply subtraction property of equality: Subtract y from each side.

x y = y y

x y = 0                (Apply Additive inverse property: y y = 0)

Compare the equation with standard form to find the values A, B and C.

The equation in standard form is x y = 0  . .
