Intro to Linear Inequalities

How many answers are there in an inequality?

• 0

• 1

• 2

• multiple

When graphing a linear inequality, < and > signs would require you to draw...

• a solid line

• a dotted line

• a solid line

• a dotted line

Which point below is NOT a part of the solution set?

• (0, 0)

• (0, 1)

• (-100, -3)

• (5, 10)

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.
