The line equation of standard form is , where A >0 & A, B,C are integers.
First find the slope
(Substitute
and
)
(Subtract:
)
(Divide:
)
Substitute slope m &
in point–slope form
(Useing distributive property:
)
(Multiply:
)
Rewriting the above equation in standard form,
\
(Subtract y from each side)
Apply Commutative property of addition: a + b = b + a.
\ (Apply additive inverse property:
)
(Apply additive identity property:
)
(Add 12 to both sides)
(Apply additive inverse property:
)
(Apply additive identity property:
)
(Subtract:
)
The line equation in standard form is .
