Graphing Linear Inequalities Quiz

What is a key difference between graphing linear equations and inequalities?

• Inequalities can have either a dotted or solid line.

• Inequalities never have a y-intercept.

• Linear equations always have a shaded region.

• Equations use a dashed line for all graphs.

For the inequality y < 1/3x - 2, what does the inequality symbol indicate about the graph?

• The line should be dotted and the region above should be shaded.

• The line should be solid and the region below should be shaded.

• The line should be dotted and the region below should be shaded.

• The line should be solid and the region above should be shaded.

What is the slope of the line for the inequality y < 1/3x - 2?

• 1/3

• 3

• -2

• -1/3

In the inequality y ≥ -2x + 2, what does the 'greater than or equal to' symbol tell us about the graph?

• The line should be dotted and the region above should be shaded.

• The line should be solid and the region below should be shaded.

• The line should be solid and the region above should be shaded.

• The line should be dotted and the region below should be shaded.

What is the y-intercept of the inequality y ≥ -2x + 2?

• 2

• 0

• -1

• -2
