Two equations. What's the solution to this system? How can you solve it? Can you write the two equations in slope-intercept form? Yes, you can. Now graph each equation. Look, the lines are parallel. What does that mean? That means there...

First, Sal defines consistent and inconsistent equations. He then evaluates a system of linear equations to determine if they are consistent or not. This resource isobviousr and would be a wonderful video to show before a test or at an...

This video lesson demonstrates how to determine if linear equations are parallel, identical, or intersecting. Students can check their understanding with an assessment.

Depending on whether and how the linear equations in a system touch each other, there will be a different number of solutions to the system. There can be one solution, no solution, and even infinite solution. Watch this video for...
