The video tutorial explains how to graph linear inequalities involving vertical and horizontal lines. It begins with an introduction to graphing inequalities and then demonstrates graphing the equation Y = -1, followed by graphing the inequality Y < -1 using test points to determine shading. The tutorial continues with graphing Y = 3 and X = 5, explaining the use of test points and shading for each. Finally, it covers graphing X < -2, emphasizing the importance of rewriting inequalities and using test points to verify solutions.

What is the first step in graphing a linear equation?

• Plotting points in a table

• Drawing a random line

• Choosing a test point

• Shading the graph

When graphing the inequality Y < -1, what does a dashed line indicate?

• The boundary line is part of the solution

• The boundary line is not part of the solution

• The inequality is greater than

• The inequality is equal to

Which test point is commonly used to determine shading in graphing inequalities?

• (0,0)

• (1,1)

• (2,2)

• (-1,-1)

In the context of graphing Y = 3, what does a solid line represent?

• The inequality is less than

• The boundary line is not part of the solution

• The boundary line is part of the solution

• The inequality is greater than

Why is testing points important when graphing inequalities?

• To calculate the midpoint

• To find the slope of the line

• To verify the accuracy of the graph

• To determine the color of the graph

When graphing X = 5, what type of line is used if the inequality is X > 5?

• Dotted line

• Curved line

• Dashed line

• Solid line

What should you do if the variable is not on the left side of the inequality?

• Ignore the inequality

• Rewrite the inequality

• Shade to the left

• Shade to the right
