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?
