# Graphing and writing inequalities

This area is the solution for the system of inequalities. Three points that are solutions are: Use a test point to determine which half plane to shade. Graph the following inequality. Horizontal and vertical lines only have 1 variable. If you don't have colored pencils, then you can draw horizontal lines for one inequality and vertical lines for the other.

Identify three points that are solutions to the inequality. This is a graph for a linear inequality. Notice that the only numbers we have in this expression are and Graph the inequality as you would a linear equation.

If the inequality symbol is greater than or equal to or less than or equal to, then you will use a solid line to indicate that the solutions are included on the boundary line. How can you verify that they are solutions. Shade the half plane that contains the solutions to the second inequality. If the inequality symbol is greater than or less than, then you will use a dotted boundary line. If the math sentence is false when you substitute 0,0then that means that 0,0 is not a solution and the other half plane or the side of the line that does not contain 0,0 should be shaded.

Steps for Graphing Systems of Inequalities Graph the boundary line for the first inequality. I hope this helps you to understand how to graph linear inequalities. Take a look at the examples below and it will all make sense. Once your linear equation is graphed, you then must focus on the inequality symbol and perform two more steps.

Steps for Graphing Systems of Inequalities Graph the boundary line for the first inequality. You may want to keep this handy for a reference. Then identify three solution to the inequality. The inequality has been maintained.

Note that the line is solid because the inequality sign is greater than or equal to. The only difference between them is the number of steps you have to perform in order to get to the solution. There is still one more step to perform and that is to divide the whole expression by Three points that are solutions are: If you have additional questions or comments, please send them via our contact form and we will try to answer them as soon as possible.

I will choose 0,0 because this is the easiest point to substitute into the inequality to check for solutions. If this all sounds confusing, don't worry But, if you follow the order of operationsremember all you have learned in previous lessons and with a bit of practice as well as logical reasoning, you will have no trouble whatsoever.

This will make it easier to see which area contains solutions for both inequalities. Since this is a true statement, 1,2 is a solution to the inequality. We need to rewrite the inequality so that it is in slope intercept form.

Since that is a negative number, keep in mind you have to change the sign of inequality to its opposite. Shade the half plane that contains the solutions to the second inequality. Since this is a true statement, 1,2 is a solution to the inequality.

Shade the solution set. The resulting value of AC Multi-step inequalities Multi-step inequalities are solved in exactly the same way as are one step inequalities or two step inequalities. It might help for you to have two different colored pencils if you are practicing along with me. Solving Inequalities Worksheets.

Solving Inequalities Worksheet 1 – Here is a twelve problem worksheet featuring simple one-step inequalities. Use inverse operations or mental math to solve for x. Solving Inequalities Worksheet 1 RTF. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

If you know two points that a line passes through, this page will show you how to find the equation of the line. When graphing any equation, it is important to keep in mind the general shape of the graph. For instance, the general shape of the graph of y = x^2 is a parabola, and.
