Introduction to Inequalities

Objective: Understand and graph inequalities

Multiple Select

WARM-UP

Which statements are true when comparing -13 and -4.

-13 > -4

-4 < -13

-13 < -4

-4 > -13

VOCABULARY

x = 5: "x equals 5" so x is 5

x < 5: "x is less than 5" so x is 4, 3, 2, 1 ,0, -1, -2 ...

x ≤ 5: "x is less than or equal to 5" so x is 5, 4, 3, 2, 1 ,0, -1, -2 ...

x > 5: "x is greater than 5" so x is 6, 7, 8, 9, 10, 11, 12 ...

x ≥ 5: "x is greater than or equal to 5" so x is 5, 6, 7, 8, 9, 10, 11, 12 ...

Match

Match the following inequalities with their translations.

x < 5

x > 5

x < -5

x > -5

x is less than five

x is greater than five

x is less than negative five

x is greater than negative five

GRAPHICAL REPRESENTATIONS

Example: x = 6

Example: x < 6

Example: x ≤ 6

Example: x > 6

Example: x ≥ 6

Match

Match the following word descriptions with their graph.

x is less than 12

x is greater than 12

x is less than or equal to 12

x is greater than or equal to 12

Match

Match the graph with the inequality.

x > 16

x < 16

x ≥ 16

x ≤ 16

What if the variable is on the right?

Circle rules are the same.

You may want to rewrite it but it has to 'eat' the same number or variable.

Example: 2 < x

Multiple Select

Which inequalities represent the graph?

x < -4

x > -4

-4 > x

-4 < x

Match

Match the Inequality with its graph.

-5 < x

-5 > x

-5 ≥ x

-5 ≤ x
