Then identify three solution to the inequality. Example 2: Rewriting the Inequality in Slope Intercept Form. To choose three solutions to the inequality. Sign is greater than or equal to, so we will graph a solid line this It's in slope intercept form before we graph. Created by Sal Khan and Monterey Institute for Technology and Education.

Is not a solution and the other half plane (or the side of the line thatįor this second example, we'll need to rewrite the equation so that Learn how to plot a simple inequality on a number line. Sentence is false when you substitute (0,0), then that means that (0,0) Solution and you shade the half plane that contains (0,0). Is true once you substitute (0,0), then that means that (0,0) is a Substitute (0,0) into the original inequality. Unsure you can always choose a test point. You may want to keep this handy for a reference.ĭid you notice how our boundary line was a dotted line because of the less than symbol that was used in the inequality?Īlso, you may have realized that you shade below the dotted lineīecause of the less than symbol in the inequality. first let's take a look at our graphing symbols. Take a look at the examples below and it will all make sense. If this all sounds confusing, don't worry. The second step will be to determine which half plane to shade. 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 many weeks can Keith withdraw money from his. Write an inequality that represents Keith's situation.

He withdraws 25 each week for food, clothes, and movie tickets. He wants to have at least 200 in the account by the end of the summer. If the inequality symbol is greater than or less than, then you will Example 1: Inequality Word Problems Keith has 500 in a savings account at the beginning of the summer. Inequality symbol will help you to determine the boundary line. So, we must use the greater than or equal to symbol. Or, click here for a more complete list of the apps we have for you. For example, Zoom Math 200 can do some algebra even if you don’t buy a Registration Key. he wants the amount in his account to be at least 200 which means 200 or greater. Try downloading Zoom Math 200 It can do everything App4Math does, plus a little bit more, even if you do not purchase a Registration Key. You would probably think that at least means less than. You will use a solid boundary line or a dashed boundary line. 500 - 25w > 200 I know you are saying, 'How did you get that inequality' I know the 'at least' part is tricky. There will be two additional steps that you must take when graphing linear inequalities.Īs shown in this image, the first step will be to determine whether In order to succeed with this lesson, you will need to remember how to graph equations using slope intercept form.
