Writing Linear Equations Given Two Points

Here is an introduction to solving simultaneous linear equations. Start by drawing a line through two points. Create a second line which goes through the intersecting point. Background knowledge of how to find the equation of a line and...

Can an equation have an infinite number of solutions? Allow your class to discover the relationship between the input and output variables in a two-variable equation. Class members explore the concept through tables and graphs and...

When presented with categorical data, a two-way frequency table is a great way to summarize the information. Pupils organize categorical data using a two-way table, then use the tables to determine missing data and to calculate simple...

Your algebra learners write linear, exponential, and quadratic equations containing the same two graph points in this collaborative task.

Being a statistician means never having to say you're certain! Learners develop two-way frequency tables and calculate conditional and independent probabilities. They understand probability as a method of making a prediction. 

Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

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.

Learn how to use an algebraic formula to find the distance between two given points on a coordinate plane.

Given two points on a line, write an equation in slope-intercept form. But what's the slope? Oh, you have to figure out the slope first. That can be done given the two points. Just use the rise over run slope formula. This isn't so hard...

Given two points on a line, write an equation in point-slope form. But what's the slope? Oh, you have to figure out the slope first. That can be done given two points. Just use the rise over run slope formula. This isn't so hard after...
