1. Standard Form: Ax + By = C
Can be used for any type of line (even a vertical line)
Standard Form must have integer coefficients, with the leading coefficient positive.
To write equations in standard form:
Simplify, including division (If all terms are divisible by a number, divide!)
Use legal algebra moves (inverse operations) to move terms to the correct location.

2. Multiply by the denominator.
Standard Form must have integer coefficients!
* To get rid of fractions:
* To get rid of decimals:
Multiply by the denominator.
Multiply by a power of 10.
(For example 10, 100, 1000, etc.)
