Master How to graph vertical and horizontal linear inequalities

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
