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.

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, or steepness, of a line is found by dividing the vertical change (rise) by the horizontal change (run). The formula is slope = (y₂ - y₁)/ (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the coordinates of two …

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).

There are three main steps to this: find the slope, find the "y"-intercept (where the graph crosses the "y"-axis), and put those values into the formula y=mx+b.

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

To know what the acceleration was at a given instant —the instantaneous acceleration —we need the slope at that instant. In other words, we need the slope of the line tangent to the curve at that time.

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

Sal determines the x-intercept of a linear equation from a graph. Afterwards, he checks his work by plugging values back into the equation.
