Will my line be solid?

x ≥ 5

• Yes

• No

Which point below is NOT part of the solution set?

• (0, 0)
• (5, 1)
• (-1, -3)
• (20, -5)

Are the points on the line part of the solution set or not? For example

• Yes, they are part of the solution set
• No, they are NOT part of the solution set

Is the point (3, 1) a solution for the following inequality? Choose the best answer that has the best explanation.

• Yes because it is located in the shaded region.

• No because it is located on the line and the line is dotted.

• Yes because it is located on the line.

• No because it is in the shaded region.

Where would you find a solution for

y < -x + 4

• In the shaded region above the line.

• In the shaded region below the line.

• On the line.

• On the origin.

How can I tell if the graph of an inequality will have a solid line?

• It has just an equal sign.
• The symbol is greater than.
• The symbol has "or equal to."
• You just guess.

Are the points on the line part of the solution set or not?
