Linear equation

Linear equations are any algebraic equations where both sides of the equation are polynomials or monomials of the first degree.

Single-Variable Equations

Single-variable linear equations can always be expressed in the form:

where and are constants and is the variable.

From this form, they can be solved with the following steps:

1. subtract from both sides.

2. divide from both sides.

Two-Variable Equations

Two-variable linear equations can always be expressed in the form:

Where and are variables and and are constants.

Two-variable linear equations can be drawn as a straight line on a coordinate plane. can be defined as the slope and can be defined as the y-intercept
