Virtual Nerd: How Do You Check if a Point Is on a Line if You Have an Equation

Can it be determined if a given point satisfies the equation and is thus a point on the line of the graph? So given a coordinate point, plug the values into the equation and solve. If the solution is true, then the given point lies on...

The instructor demonstrates how to verify that a given point does or does not lie on the line of a given equation. She draws a graph (the axis lines need arrow ends) and plots the given linear equation. She then plots the coordinate...

The instructor demonstrates graphically how to verify that a given point lies on the line of a given equation. She graphs a line in slope-intercept form, and then plots the point to verify if it is in fact, on the graph of the line.

In this video lesson students learn how to graph data on a coordinate plane and draw a line of fit for that data.

Show your class how to check their answers for a system of linear equations. This video clarifies how to plug in answers and solve each equation. This is a straightforward video that could be useful to learners as the work on their...

Fractions and variables on both sides of the equation? Oh my! There are one hundred and one steps to solving this equation. Not really, but now that I have your attention, I recommend you watch this video closely and follow the...

This tutorial demonstrates how to solve a multi-step equation for a variable. A step by step process is given with examples. [3:45]

To graph a function, you first need a table of values to fit your equation. This video will demonstrate how to make a table and then plot those values to make a graph. [3:23]

To graph a linear equation, you first need to make a table of values to plot. This tutorial will teach you how to set up this table of values using an example. [5:41]
