### Graphing Inequalities

Standard: Solve and graph inequalities in one variable.

Essential Question: How can I graph an inequality?

An inequality is a sentence that contains a <, >, <, or > sign.

Examples:

x < 3 is read “x is less than three”

x > 3 is read “x is greater than three”

x< 3 is read “x is less than or equal to three”

x> 3 is read “x is greater than or equal to three”

To graph x < 3, put at least 3 points on the number line with 3 (boundary point) in the middle. Place one number less than the boundary point and one number greater than the boundary point.

Then circle the boundary point. Since x < 3, this means that the values for x can be any number less than 3. Show this on the graph by shading numbers less than 3.

To graph x > 3, put at least 3 points on the number line with 3 (boundary point) in the middle. Place one number less than the boundary point and one number greater than the boundary point.

Then circle the boundary point. Since x > 3, this means that the values for x can be any number greater than 3. Show this on the graph by shading numbers greater than 3.

To graph x that the values for x can be any number greater than 3. Show this on the graph by shading numbers greater than 3.< 3, put at least 3 points on the number line with 3 (boundary point) in the middle. Place one number less than the boundary point and one number greater than the boundary point.

Then circle the boundary point. Since x that the values for x can be any number greater than 3. Show this on the graph by shading numbers greater than 3.< 3, this means that the values for x can be any number less than 3 or equal to three. Show this on the graph by shading numbers less than 3. How can we show that the solution could be equal to three as well?

Fill in the circle! that the values for x can be any number greater than 3. Show this on the graph by shading numbers greater than 3.

To graph x that the values for x can be any number greater than 3. Show this on the graph by shading numbers greater than 3.> 3, put at least 3 points on the number line with 3 (boundary point) in the middle. Place one number less than the boundary point and one number greater than the boundary point.

Try these on your own. that the values for x can be any number greater than 3. Show this on the graph by shading numbers greater than 3.
