Graphing and Interpreting Linear Equations in Two Variables

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...

Add more points on the graph ... and it still remains a line! The 13th installment in a series of 33 leads the class to the understanding that the graph of linear equation is a line. Pupils find several solutions to a two-variable linear...

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...

Show your class that linear equations produce graphs of lines. The 20th segment in a unit of 33 provides proof that the graph of a two-variable linear equation is a line. Scholars graph linear equations using two points, either from...

Introduce young mathematicians to a different kind of two step. Using four different equations, the resource reinforces the steps to solving a two-step linear equation. The video works each problem and demonstrates how to isolate the...

Everything you need to teach a lesson on two variable linear equations is right here. Objective, vocabulary, tech tips videos, and multiple downloadable files are all included. Learners will use the TI-Nspire technology to determine the...

There are many ways to solve a quadratic equation. Let's check out how to solve a quadratic equation by graphing. But first, let's find the axis of symmetry and the vertex before making a table of values. Write the values as ordered...

In this exercise, students practice graphing solutions to two-variable linear equations. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

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...

Approach inequalities in a new way with this video! This video gives step-by-step instruction on how to solve a two step inequality and then graph the answer. Learners could use this video as a reference as they do homework, or you might...
