Graphing Linear Inequalities in Two Variables

What is the preferred form for writing equations when graphing linear inequalities?

• Point-slope form

• Standard form

• Slope-intercept form

• Quadratic form

Which symbol represents a 'greater than' inequality?

• <

• >

• ≤

• ≥

How do you represent a 'less than or equal to' inequality on a graph?

• With a solid line

• With a dashed line

• With a dotted line

• With a bold line

What type of line is represented by the equation x = 3?

• Horizontal line

• Curved line

• Vertical line

• Diagonal line

When graphing the inequality y < -4, what type of line should be used?

What is the slope in the equation y = 2/3x + 2?

• 2

• 3

• 1/2

• 2/3

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

• It becomes an equal sign

• It changes direction

• It stays the same

• It disappears

In the inequality y < -1/4x + 1, where do you start graphing on the y-axis?

• At 0

• At -1
