Learn how to graph and shade a system of linear inequalities in two different ways

The video tutorial explains how to graph linear systems of inequalities by first graphing each inequality separately and then applying shading to determine the solution region. It covers rewriting equations to facilitate graphing, using the intercept method to find X and Y intercepts, and graphing in slope-intercept form. The tutorial also discusses how to determine shading and boundary lines based on inequality symbols.

What is the first step in graphing a system of linear inequalities?

• Finding the slope

• Determining the shading

• Rewriting the equations

• Plotting the points

In the intercept method, what is the X-intercept?

• When X = 0

• When Y = 0

• When X = Y

• When X and Y are equal

Why is the intercept method useful in graphing?

• It avoids fractions

• It uses only positive numbers

• It requires no calculations

• It is faster than other methods

What is the advantage of using slope-intercept form?

• It requires no calculations

• It quickly identifies slope and Y-intercept

• It is the only method for graphing

• It avoids negative numbers

How do you determine the slope from the equation in slope-intercept form?

• By dividing the coefficients

• By identifying the coefficient of X

• By looking at the Y-intercept

• By subtracting the Y-intercept from X

What is the purpose of using a test point in graphing inequalities?

• To verify the line equation

• To determine the shading region

• To calculate the intercepts

• To find the slope

Which point is commonly used as a test point for shading?

• (3,3)

• (2,2)

• (0,0)

• (1,1)
