What is Slope?

Slope measures the steepness and direction of a line between two points, calculated as the change in y over the change in x. It quantifies incline and decline, essential for linear equations and graphical analysis.

2.1 Definition and Basic Understanding

Slope is a measure of the steepness and direction of a line between two points. It is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points. Mathematically, slope (m) is defined as ( m = rac{y_2 ⎼ y_1}{x_2 ⎼ x_1} ), where ((x_1, y_1)) and ((x_2, y_2)) are the coordinates of the two points. A positive slope indicates a line rising from left to right, while a negative slope indicates a line falling. A slope of zero means the line is horizontal, and an undefined slope (infinite) means the line is vertical. Understanding slope is foundational for graphing and analyzing linear relationships in mathematics and real-world applications.

2.2 Slope in Coordinate Geometry

Slope is a fundamental concept in coordinate geometry, describing the inclination of a line between two points. It is calculated using the formula ( m = rac{y_2 ─ y_1}{x_2 ─ x_1} ), where ( (x_1, y_1) ) and ( (x_2, y_2) ) are the coordinates of two points. This measure helps determine the direction and steepness of the line. A positive slope indicates an upward incline, while a negative slope shows a downward incline. In coordinate geometry, slope is essential for graphing linear equations, identifying parallel or perpendicular lines, and solving real-world problems involving rates of change, such as velocity or acceleration.
