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.
\ (Add 25 to each side.)
(Apply Additive inverse property:
)
(Subtract 5y from each side)
(Apply Commutative property: a + b = b + a)
(Apply Addtive inverse property:
)
According to division property of equality: if , then
.
(Divide each side by 5)
(Apply Distributive property:
)
(Cancel common terms)
(Divide:
)
