Virtual Nerd: Determine if an Ordered Pair Is a Solution to a Linear Inequality

An intersection is more than just the point where lines intersect; explain this and the meaning of the intersection to your class. The 26th segment in a 33-part series uses graphing to solve systems of equations. Pupils graph linear...

Middle and high schoolers solve four word problems based on three different graphs of ordered pairs which show the amount of money spent on lunch on particular days. Next, learners are given two equations of functions, and an x value and...

Systematically check a solution in a system. Given a point and a system, the presenter checks to see if the point is a solution to the system. Pupils understand what it means to be a solution to a system. The video shows both...

How can one equation have more than one solution? Well, if it has two variables, the solutions can be endless! Individuals explore the concept using a video tutorial that demonstrates finding multiple solutions to a linear equation in...

Check to see if a given ordered pair is a solution to an inequality. Just plug the given values into the given inequality and do the math. If the resulting statement is true then the given ordered pair is a solution. If the statement is...

There are several ways to determine if an ordered pair is the solution to a linear equation. The ordered pair can be plugged in to the equation to check if it's a solution. However, in this video the instructor sets up a table and plugs...

Order is important! An ordered pair is comprised of an x-value, and a y-value. The x-value always comes first. This ordered pair represents a point on a coordinate plane. If the order of the x-value and the y-value are switched then they...

Using an amusing amusement park, Sam describes how it is a coordinate plane and how to graph an ordered pair. Perfect for beginners, the animation moves on to point out a tip using the first quadrant of an empty coordinate plane.

An ordered pair is comprised of an x-value, and a y-value. The x-value always comes first, then the y-value in an ordered pair. This ordered pair represents a point on a coordinate plane. There are many meanings of an ordered pair and...

The video demonstrates how to determine if an ordered pair is a solution to a specified linear equation. The example shown demonstrates how to do this by using substitution. It also mentions that this problem can be solved by graphing...
