Mastering One Step Addition and Subtraction Inequalities

Mrs. Walker introduces solving one-step addition and subtraction inequalities, starting with a review of graphing techniques using open and closed dots. She provides examples to demonstrate solving inequalities by isolating variables using inverse operations and graphing the solutions. The video covers four examples, each illustrating different inequality scenarios and graphing methods.

What is the first step in solving one-step addition and subtraction inequalities?

• Subtracting a constant

• Adding a constant

• Isolating the variable

• Graphing the inequality

What does an open dot on a graph indicate?

• The number is greater than the solution

• The number is not included in the solution

• The number is less than the solution

• The number is included in the solution

Which symbol is used to represent a closed dot?

• Not equal to

• Less than or equal to

• Greater than

• Less than

In the example 'X is less than 4', which direction does the arrow point on the graph?

• Up

• Down

• Right

• Left

What is the inverse operation of adding 13?
