Chapter Overview
This chapter focuses on the geometric and algebraic aspects of straight lines in a coordinate plane. It covers different forms of the equation of a line, concepts of slope, angles between lines, distance from a point to a line, and conditions for parallelism and perpendicularity. These ideas form the foundation for higher studies in geometry, calculus, and vector algebra.
Important Keywords
- Coordinate Plane: A two-dimensional surface defined by an x-axis and y-axis.
- Slope (m): Measure of the steepness of a line.
- Intercept: The point where a line crosses the x-axis or y-axis.
- Angle Between Lines: The angle formed at the intersection of two lines.
- Collinearity: Condition when three or more points lie on the same straight line.
