      How Do You Make a Table of Values for a Linear Equation?

      To graph a linear equation, you could make a table of values to plot, but first you'll need to know how to make the table. Take a look at this tutorial! You'll see how to set up a table, choose appropriate x-values, plug those values into the equation, and simplify to get the respective y-values. This tutorial shows you how to set up a table of values for a linear equation!

      What Does the Slope of a Line Mean?

      You can't learn about linear equations without learning about slope. The slope of a line is the steepness of the line. There are many ways to think about slope. Slope is the rise over the run, the change in 'y' over the change in 'x', or the gradient of a line. Check out this tutorial to learn about slope!
