1. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable raised to the first power.
2. The graph of a linear equation is a straight line.
3. The general form of a linear equation is Ax + By = C, where A, B, and C are constants, and x and y are variables.
4. Linear equations can have one, infinite, or no solutions.
5. Linear equations can be solved using various methods such as substitution, elimination, and graphing.
6. Linear equations can be used to represent relationships between variables in real-world situations, such as distance, time, and cost.

- The equation is written in the form y = mx + b, where m is the slope of the line and b is the y-intercept. - The graph of a linear equation is a straight line. - The slope of a line is the ratio of the change in y to the change in x. - The y-intercept of a line is the point where the line crosses the y-axis. - Two lines are parallel if they have the same slope. - Two lines are perpendicular if their slopes are negative reciprocals of each other.
