Learn how to write the slope formula from scratch and how to apply it to find the slope of a line from two points.

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Learn how to calculate the slope of the line in a graph by finding the change in y and the change in x. Created by Sal Khan and Monterey Institute for Technology and Education.

Given two points on a line, you can find the slope of the line. Watch Sal doing a bunch of examples.

Slope tells us how steep a line is. It's like measuring how quickly a hill goes up or down. We find the slope by seeing how much we go up or down (vertical change) for each step to the right …

Course: Algebra 1 > Unit 4 Lesson 2: Slope Intro to slope Positive & negative slope Worked example: slope from graph

Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). Topics you'll explore include the slope and the equation of a line.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.
