The linear function is .
Rewrite the equation in standard form Ax + By = C.
\According to addition property of equality: if a = b, then a + c = b + c.
\ \ \ (Subtract 4y from each side.)
(Apply Commutative property: a + b = b + a)
(Apply Additive inverse property:
)
Compare the equation with standard form to find the values A, B and C.
\The equation in standard form is .
