Slope-intercept equation from graph (video) | Khan Academy
When you try to write a slope-intercept equation from a graph, there are three steps you need to take: 1. Slope Remember that slope is rise/run, or change in y over change in x. Find two points on the line …
Slope review | Algebra (article) | Khan Academy
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 the basics of slope and its application in linear equations and graphs with this introductory video tutorial.
Point-slope & slope-intercept equations - Khan Academy
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). We can rewrite an equation in point-slope form to be in …
Calculating the rate of change of a linear function
From a table of a linear function, find the change in output values divided by the change in input values. From a graph, choose two points and find this same quotient. From an equation, rewrite it in slope …

Walk through a graphical explanation of how to find the slope from two points and what it means.
Worked example: slope from two points (video) | Khan Academy
Let's find the slope of the line that goes through the ordered pairs (4,2) and (-3, 16). The slope, or steepness, of a line is found by dividing the vertical change (rise) by the horizontal change (run). The …
