Learn how to graph and shade a linear inequality that is horizontal

The video tutorial explains how to graph linear inequalities, focusing on identifying line types, solving for Y, and graphing equations with one variable. It covers horizontal lines and testing points to verify solutions, emphasizing the difference between solid and dashed lines in inequalities.

What type of line is used when graphing a 'less than or equal to' inequality?

• Dotted line

• Curved line

• Solid line

• Dashed line

When solving for Y in an inequality, what must you do if you divide by a negative number?

• Subtract a constant from both sides

• Add a constant to both sides

• Multiply by a positive number

• Flip the inequality sign

In the equation Y = 2, what type of line does this represent on a graph?

• Vertical line

• Diagonal line

• Horizontal line

• Curved line

How do you determine if a point is a solution to a linear inequality?

• Check if the point lies on the line

• Test the point in the inequality

• Ensure the point is above the line

• Ensure the point is below the line

What is the best test point to use when checking solutions for a linear inequality?

• (1,1)

• (2,2)

• (0,0)

• (-1,-1)
