Virtual Nerd: How Do You Graph a Linear Equation by Making a Table?

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to word problems that are more complicated.

Graph a linear equation by creating a table to get some values to plot. Select some values for x and plug them into the equation to get the y values. The x and y values make ordered pairs that can be plotted on the graph. After plotting...

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]

This tutorial will teach you how to graph the union of two inequalities using a number line. [2:06]

The intersection of two inequalities is what they have in common. This tutorial shows you how to graph two inequalities on the same number line and then find the intersection. [2:40]

This tutorial will demonstrate how to graph an inequality and an infinite set on a number line. Closed and open circles are discussed using specific examples. [3:37]

Make a table to graph a rational equation. Make a list of values for x and plug them into the expression to get the y value. Then plot the ordered pairs on a graph. Hey, this graph looks funny! Something about asymptotes. Watch closely...

Do you know how to graph a linear equation? If you do then graphing an inequality will not be a problem for you. There are a couple of differences: is the line solid or dashed, and which half plane do you have to shade. Watch this video...

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

Probability is the likelihood that a given event will take place. So how do you determine the probability of a simple event? Watch this example using marbles for an explanation. [4:36]
