How to Find the Slope of a Line

Table the decision to land. Pupils form flight crews by matching up different representations of linear equations. Given a set of coordinates for an airstrip, the crews determine the equation of the line that will position their planes...

Challenge the class to determine the equation of a line. The 21st part in a 33-part series begins with a proof that every line is a graph of a linear equation. Pupils use that information to find the slope-intercept form of the equation...

Given a graphed line, can you find the slope of the line? In this video, Sal shows how to calculate the change in y over the change in x. He also shows how one can pick any two points on line and still calculate the same slope.

Discover the parallel structure of parallel lines. Provided with two parallel lines on a coordinate plane, the presenter shows that the rise and run, or slope, of the two lines are the same. The resource, which is a portion of a larger...

Don't make a mountain out of finding slope. Learners find out how to determine the slope of a line graphed on the coordinate plane. Given a point and the slope of a line, pupils graph the line. Using the definition of slope, they then...

Explain how to find the slope of a graph of a line with a video that points out how no matter what two points are used on a graph of a line, the slope is the same. A few examples reiterate how to find the slope of vertical and horizontal...

Slope is the steepness of a line, but how do you quantify steepness? A video demonstrates how to find the slope of a line from a graph, either by counting vertical and horizontal change or by using the slope formula. Five problem videos...

The teacher demonstrates how to plug in values from two given points to find the slope of a line. She uses the slope formula and goes through the problem step-by-step.

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The lesson also includes the discussion of slopes of parallel and...

Add depth to your class' understanding of fractions with video seven of this nine-part series. Building on prior experience representing fractions on number lines, young mathematicians learn to identify and extend patterns involving the...
