Graphing a linear vertical inequality with a dashed boundary line

The video tutorial explains how to graph the inequality X > 3. It begins by discussing various methods for graphing, such as finding intercepts and using slope-intercept form, but focuses on a simpler approach. The tutorial demonstrates graphing the line X = 3 as a vertical boundary line and explains the use of a dashed line to indicate that X = 3 is not part of the solution. It also covers using test points to determine which side of the boundary line contains the solution set, emphasizing that points to the right of the line are true solutions. The video concludes with a summary of the graphing process.

What type of line is used to graph the equation X = 3?

• Diagonal line

• Vertical line

• Horizontal line

• Curved line

Why is the boundary line dashed when graphing X > 3?

• Because it is a horizontal line

• Because X = 3 is not part of the solution

• Because it is a curved line

• Because X = 3 is part of the solution

What is the purpose of using test points in graphing inequalities?

• To find the slope of the line

• To determine the intercepts

• To verify which side of the boundary line is the solution

• To calculate the distance between points

Which of the following points would be part of the solution set for X > 3?

• (0, 0)

• (2, 0)

• (3, 0)

• (4, 0)

What does shading on the graph represent in the context of inequalities?

• The slope of the line

• The intercepts

• The solution set

• The boundary line
