Which of the following signs represents 'greater than or equal to'?

• >

• <

• ≥

• ≤

What type of line is used to graph y ≥ 3x + 2?

• Dashed

• Curved

• Dotted

• Solid

Where do you start plotting the graph for y ≥ 3x + 2?

• At the x-intercept

• At the y-intercept

• At any random point

• At the origin

What is the slope (m) of the line y ≥ 3x + 2?

• 1

• -1

• 3

• 2

For the inequality y ≤ -x - 2, what is the y-intercept (b)?

• 1

• -2

• 2

• -1

What type of line is used to graph y ≤ -x - 2?

• Curved

• Solid

• Dashed

• Dotted

In which direction do you shade for the inequality y ≤ -x - 2?

• Below the line

• Above the line

• To the left of the line

• To the right of the line

When combining two inequalities on the same graph, what are you looking for?

• The intersection of the lines

• The union of the shaded regions

• The area where both shaded regions overlap

• The area where neither shaded region exists

What is the solution to a system of inequalities?

• The area outside the shaded regions

• The area where the shaded regions overlap

• Any point on the graph

• The intersection point of the lines

How can you verify the shaded region for an inequality?

• By drawing a random line

• By checking the y-intercept

• By checking the slope

• By picking a point in the region and substituting it into the inequality
