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

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.

Walk through a graphical explanation of how to find the slope from two points and what it means. We can draw a line through any two points on the coordinate plane. Let's take the points (3, 2) and (5, 8) …

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 (horizontal …

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.

Worked examples of finding the slope of a line given its equation, using many forms of equations.

Walk through a graphical explanation of how to find the slope from two points and what it means.

Slope-intercept form (y=mx+b) of linear equations highlights the slope (m) and the y-intercept (b) of a line. Watch this video to learn more about it and see some examples.

Learn about the slope-intercept form of two-variable linear equations, and how to interpret it to find the slope and y-intercept of their line.
