What's My Rule? Simple Linear Functions

Here is a well-designed resource that provides five yes-or-no questions which model different situations with linear functions. It makes a good pre-test for the beginning of the unit. The purpose is to elicit common misconceptions of...

This lesson begins with a review of linear functions and segues nicely over its fifteen examples and problems into a deep study of exponential functions. Linear and exponential growth are compared in an investment task. Data tables are...

Illuminate the world of mathematics for your class, specifically, the process of linear equations. In this video, Sal teaches about linear equations in standard form after two videos on slope-intercept and slope-point forms. He defines...

Viewers play a game with Sal, in which he presents three different data sets that come from either linear, quadratic, or exponential functions. In solving this puzzle, Sal manages to not only provide a strong definition of each function,...

Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.

How many ways can you write a linear equation? Lots! Each form has its purpose in the world of algebra, so do you know how to write it in standard form? Ax+by=c. This is what standard form looks like. Can you rearrange the given equation...

Given the coordinates for a point on a line and given the slope of that line, write an equation in point-slope form. Really, all that needs to be done is to use the formula for point-slope form and plug in the values.

How many ways can you write a linear equation? Yep, lots! Each form has it's purpose in the world of Algebra, so do you know how to write it in standard form? Ax+by=c. This is what standard form looks like. Can you rearrange the given...

There's just something special about lines in algebra. Introduce your classes to linear equations by analyzing the linear relationship. Young mathematicians use input/output pairs to determine the slope and the slope-intercept formula to...

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...
