Graphing Linear Inequalities Quiz

What is the first step in graphing a linear inequality?

• Convert it to standard form

• Convert it to slope-intercept form

• Find the y-intercept

• Find the x-intercept

When graphing a linear inequality, what does a solid line indicate?

• The inequality is strict

• The solutions include the line

• The solutions exclude the line

• The inequality is undefined

How do you determine which side of the line to shade for a linear inequality?

• Shade above for less than

• Shade below for greater than

• Use a test point to determine shading

• Always shade towards the origin

In the first example, what type of line is used for the inequality y < 1/2x + 4?

• Solid line

• Dashed line

• Vertical line

• Horizontal line

For the inequality y > -1/3x - 2, what is the correct shading direction?

• Shade above the line

• Shade to the right of the line

• Shade below the line

• Shade to the left of the line

What happens to the inequality sign when you divide by a negative number?

• It becomes undefined

• It becomes an equal sign

• It stays the same

• It flips direction

In the example of x < 2, what type of line is used?
