Symbol Meaning Graph

< Less than Open circle

> Greater than Open circle

≤ Less than or equal to Closed circle

≥ Greater than or equal to

Closed circle

Page 3: Solving One-Step Inequalities

Let’s think ………

1,0,-1,-2,-3…

What about… ½ or 1.999999?

This is why we use an open circle when we graph the inequality

x< 2

Is 2 less than 2?

Page 4: Solving One-Step Inequalities

The open circle tells us that 2 is not included

Page 5: Solving One-Step Inequalities

Graph x > 2

Where do we put the circle ?

In which direction does the arrow go?

Think…what could you plug in for x that is greater than 2?

Page 6: Solving One-Step Inequalities

What about x ≤ 2 ……is 2 ≤ 2

Which way does the arrow go?

Page 7: Solving One-Step Inequalities

What about x ≥ 2 ……is 2 ≥ 2

Which way does the arrow go?

Where do we put the circle ?

Page 8: Solving One-Step Inequalities

1.Write the inequality above the number line.

2.Graph the inequality.

1) x > 82) x< 73) x ≤ 44) x ≥ -35) x < -56) x ≤ 6
