💻IM1 Graphing Linear Inequalities

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.

Which of the following is "NOT" a solution for the inequality?

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

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

• A dotted line

• A solid line

• Shade up

• Shade down

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

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

• It has an equal sign.

• The symbol is greater than or less than.

• The symbol has "or equal to."

• You just guess.

Slope is describe as

• solid
