Understanding Inequalities on Number Lines and Coordinate Planes

The video tutorial explains how to represent the inequality y > 5 on both a number line and a coordinate plane. It begins with drawing a number line, marking the number 5 with an open circle to indicate that 5 is not included, and shading the area to the right to show all values greater than 5. The tutorial then moves to the coordinate plane, where a dotted line is drawn at y = 5, and the area above this line is shaded to represent all y values greater than 5. The video emphasizes the difference between 'greater than' and 'greater than or equal to' in both representations.

What is the main task described in the video?

• Finding the value of y

• Drawing a graph

• Representing an inequality

• Solving an equation

How is the number 5 represented on the number line for the inequality y > 5?

• With an open circle

• With a triangle

• With a square

• With a filled circle

What does an open circle on a number line indicate?

• The number is not included

• The number is included

• The number is a minimum

• The number is a maximum

What is the first step in representing the inequality on a coordinate plane?

• Labeling the points

• Drawing a dotted line

• Shading the area

• Drawing the axes

How is the line y = 5 represented on the coordinate plane for the inequality y > 5?

• With a double line

• With a bold line

• With a dashed line

• With a solid line

What does shading above the line y = 5 on the coordinate plane indicate?

• Values less than 5

• Values equal to 5

• Values not equal to 5

• Values greater than 5

What does the dotted line at y = 5 signify on the coordinate plane?

• y is included

• y is not included

• y is a maximum

• y is a minimum

What is the significance of the shading on the coordinate plane?

• It shows minimum values

• It shows maximum values

• It shows included values

• It shows excluded values

If the inequality were y ≥ 5, how would the representation change on the number line?

• Use a dashed line

• Use a triangle

• Use a double line

• Use a filled circle

What would be the representation on the coordinate plane if the inequality were y ≥ 5?

• A dashed line

• A thin line

• A dotted line

• A bold line
