ALG2 How to graph the identify equation for an inequality

The video tutorial explains how to graph inequalities by converting them into equations and using slope-intercept form. It discusses the importance of test points in determining which side of the line to shade. The tutorial emphasizes the use of alternative test points when the line passes through the origin. It concludes with insights into understanding mathematical concepts.

What is the first step to take when you get stuck graphing an inequality?

• Convert the inequality to an equation

• Guess the graph

• Use a calculator

• Ignore the inequality

How do you determine whether to use a dashed or solid line when graphing an inequality?

• Solid for 'greater than' and dashed for 'less than'

• Dashed for 'greater than' or 'less than' and solid for 'greater than or equal to' or 'less than or equal to'

• Dashed for 'greater than or equal to' and solid for 'less than or equal to'

• Dashed for 'greater than' and solid for 'less than'

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

• To find the slope of the line

• To determine which side of the line to shade

• To check if the line is dashed or solid

• To calculate the y-intercept

Which test point is commonly used but not suitable if the line passes through it?

• (1,0)

• (1,1)

• (0,0)

• (2,2)

If a test point is false, where should you shade on the graph?

• Above the line

• On the opposite side of the line

• Below the line

• On the line
