Proving Slope Criteria for Parallel & Perpendicular Lines
This lesson launches with learners graphing the fourth vertex of a given rectangle, and finding the length and slope of one of its sides; and ends with learners writing a summary sheet for parallel and perpendicular lines. In between,...

New Review There is Only One Line Passing Through a Given Point with a Given Slope
Prove that an equation in slope-intercept form names only one line. At the beginning, the teacher leads the class through a proof that there is only one line passing through a given point with a given slope using contradiction. The 19th...

New Review Every Line is a Graph of a Linear Equation
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...

Graphing Equations on the Cartesian Plane: Slope
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...

Finding the Slope of a Line from a Graph - Concept
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...
