The video tutorial introduces graphing linear inequalities, explaining what constitutes a solution. It provides examples of solving inequalities by substituting values into equations to verify if they satisfy the inequality. The tutorial concludes with a practice problem for viewers to solve independently.

What is the first step in graphing linear inequalities?

• Finding the slope

• Calculating the x-intercept

• Understanding the solution set

• Identifying the y-intercept

What does a solution to a linear inequality represent?

• A single number

• An ordered pair

• A line

• A graph

What is the purpose of substituting values into a linear inequality?

• To determine if the inequality is true

• To find the slope

• To graph the inequality

• To find the intercepts

In the inequality 4x - 5y ≥ 12, what happens when x = 5 and y = -1?

• The inequality is not satisfied

• The inequality is satisfied

• The inequality becomes an equation

• The inequality is undefined

What does the inequality 4x - 5y ≥ 12 become when x = 5 and y = -1?

• 4x - 5y = 25

• 4x - 5y > 12

• 4x - 5y < 12

• 4x - 5y = 12
