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 more complex word problems.

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...

Watch this tutorial to learn how to graph a quadratic equation to find the solution. [7:48]

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...

How do you simplify expressions that have negative exponents? This video will walk you through the process and provide examples. [3:39]

Follow along with this tutorial to see how to take an equation in intercept form and use it to find the x-intercepts, vertex, and axis of symmetry. [6:38]

Discover how to solve two equations each with the same two unknown variables by watching the step-by-step method in this video tutorial. [3:28]

It's important to know about the parent function graph first when dealing with graphs of quadratic equations. All graphs of quadratic equations start off looking like this before their transformed. Take a look. [7:06]
