How is slope calculated between two points?

Slope is calculated as m = (y2 - y1) / (x2 - x1), representing the vertical change (rise) divided by the horizontal change (run).

What is the slope of perpendicular lines?

Two non-vertical lines are perpendicular if their slopes are negative reciprocals of each other: m1 × m2 = -1, or m2 = -1 / m1.

Understanding Slope & Line Steepness

In coordinate geometry, the slope of a line describes both its direction (positive for rising, negative for falling) and its steepness. It measures how much the dependent variable y changes for every unit increase in the independent variable x.

Frequently Asked Questions

What does an undefined slope mean?

A vertical line has an undefined slope because the horizontal change (run) is zero, and division by zero is mathematically undefined. Its equation is given by x = constant.
