Introduction to Linear Equations

Linear equations form the backbone of algebra and are essential to understanding advanced mathematical concepts. They describe a straight line when graphed on a coordinate plane, taking the general form y = mx + b.

Key Concepts

• Variable (x): A symbol that represents an unknown value.
• Slope (m): A number that represents the steepness and direction of the line.
• Y-intercept (b): The point where the line crosses the y-axis.
