Comparing Graphs of Equalities and Inequalities
Not what you're looking for?
You are preparing for an upcoming sales meeting and need to create and compare various supply and demand graphs that show the break-even point for the company. You have already compared the graphs of linear equations with those of linear inequalities. Now you will make the same comparison with financial numbers.
Consider first a linear equation of the form 2x-5y= 8
Now choose a linear inequality of the form 5 < 2x - 8 or 5 > 2x - 8
What are the major differences between the linear equation graph and the linear equality graph?
In what ways can you present these graphs to help your company understand them better?
