In this lesson we are going to look at graphing inequalities using two variables. In order to make this process work out, we will first briefly review how to just simply graph lines. We will see how this works with our inequalities which involved entire regions of our graph. The important part for highlighting these regions will be shading in the proper part of the graph. To graph an inequality in two variables begin by graphing the corresponding line. It should be dotted if the inequality is strict, and solid if the inequality has or equal. To graph the line, remember you can use slope-intercept form with the y-intercept and the slope to graph it quickly.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
