اختبار إلكتروني: Find Slope and Linear Equations

Slope is a fundamental concept in algebra that describes the steepness and direction of a line. It is defined as the ratio of the vertical change (the rise) to the horizontal change (the run) between any two distinct points on a line. For a horizontal line, the rise is zero, resulting in a slope of zero. Conversely, a vertical line has a run of zero, which makes its slope undefined due to the impossibility of division by zero. By using the slope formula \(m = \frac{y_2 - y_1}{x_2 - x_1}\), one can calculate the slope from given coordinates or identify it from a graph. Understanding these properties is essential for solving linear equations and analyzing the behavior of functions.
