Understanding Linear Equations

Linear equations are fundamental to algebra and have numerous real-world applications. They can be expressed in three main forms:

Standard Form: Ax + By = C

This is the most general form where A, B, and C are constants and A and B are not both zero.

Slope-Intercept Form: y = mx + b

Where m is the slope and b is the y-intercept. This form is particularly useful for graphing.

Point-Slope Form: y - y₁ = m(x - x₁)

This form is helpful when you know a point on the line and its slope.
