Adding and Subtracting Rational Expressions

What symbol is used in a linear inequality instead of an equals sign?

• Division symbol

• Inequality symbol

• Addition symbol

• Multiplication symbol

If the ordered pair (2, 5) is plugged into the inequality 2x - 3y < 15, what is the result?

• No solution

• Undefined

• False

• True

Which ordered pair does NOT satisfy the inequality 2x - 3y < 15?

• (0, 0)

• (-1, -7)

• (2, 5)

• (3, -4)

What is the first step in graphing a linear inequality?

• Plotting points

• Converting to slope-intercept form

• Drawing the line

• Shading the area

What type of line is used to graph an inequality that includes an 'or equal to' condition?

• Dotted line

• Wavy line

• Solid line

• No line

In the inequality y > 2/3x - 5, where should you shade on the graph?

• Below the line

• No shading needed

• Above the line

• On the line

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

• It remains the same

• It disappears

• It flips

• It becomes an equals sign

If the slope (m) is 2/3 and y-intercept (b) is -5, how do you plot the first point for the graph?

• At (0, -5)

• At (2/3, 0)

• At (-5, 0)

• At (0, 2/3)

For the inequality y > 1/3x - 5, which type of line should be used on the graph?

• No line

• Thick line

• Dotted line

• Solid line

When graphing the inequality y < -2x - 1, where should the shading be applied?

• Above the line

• Below the line

• On the line

• No shading
