Writing Inequalities from Number-Line Graphs

What is the first step in writing an inequality from a graph?

• Choosing a variable

• Placing the inequality symbol

• Identifying the endpoint

• Drawing the number line

If no variable is given, what can you do?

• Use the letter 'y' by default

• Use the letter 'x' by default

• Choose any letter you like

• Leave it blank

What determines the direction of the inequality symbol?

• The type of endpoint

• The direction the graph points

• The number line

• The position of the variable

What does a solid dot at the endpoint indicate?

• A variable

• An 'or equal to' inequality

• An open circle

• A strict inequality

In the example with the endpoint at -3, what is the inequality?

• f ≥ -3

• f ≤ -3

• f > -3

• f < -3

What does an open circle at the endpoint indicate?

• A strict inequality

• A variable

• An 'or equal to' inequality

• A solid dot

In the example with the endpoint at 5, what is the inequality?

• c < 5

• c > 5

• c ≤ 5

• c ≥ 5

In the example with the endpoint at -7, what is the inequality?

• x ≤ -7

• x ≥ -7

• x > -7

• x < -7

What is the rule for the direction of the inequality when the variable is first?

• It points in the opposite direction of the graph

• It points in the same direction as the graph

• It always points to the left

• It always points to the right

What should you do if the graph points to the left and the endpoint is an open circle?

• Use a 'less than or equal to' symbol

• Use a 'greater than or equal to' symbol

• Use a 'less than' symbol

• Use a 'greater than' symbol
