Writing the inequality from the graph - Math Homework Answers

The video tutorial explains how to graph inequalities by identifying whether values are less than or greater than a given point. It covers the use of variables to represent a range of numbers and explains the significance of open and closed dots in graphing. The lesson concludes with a summary of the key points discussed.

What is the first step when given a graph to determine the inequality?

• Calculate the slope of the graph.

• Draw a line through the graph.

• Find the midpoint of the graph.

• Identify the main point and determine if values are less than or greater than it.

How can you represent all numbers less than a specific value on a graph?

• By using a variable like X.

• By using a specific number.

• By using a greater than symbol.

• By drawing a line.

Which symbol is used to represent numbers less than a given value?

• Not equal to symbol

• Less than symbol

• Greater than symbol

• Equal to symbol

What does an open dot on a graph signify?

• The inequality is greater than or equal to.

• The point is not included in the inequality.

• The point is included in the inequality.

• The inequality is less than or equal to.

What is the difference between an open dot and a closed dot on a graph?

• Open dot includes the point, closed dot does not.

• Open dot does not include the point, closed dot includes it.

• Both include the point.

• Neither include the point.
