Unit 2B Review

Front

What type of line is used when graphing an inequality with the symbols < or >?

Back

A dashed line is used.

Front

Which point is NOT a solution to the system of inequalities: (0,-1), (0,3), (4,0), (6,-2)?

Back

(0,-1) is NOT a solution.

Front

Which point is NOT a solution to the inequality shown on the graph: (-5, 1), (3, 0), (6, 2), (0, 6)?

Back

(-5, 1) is NOT a solution.

Front

What system of inequalities models the situation: A deli sells ham subs (h) for $6 each and meatball subs (m) for $8 each, selling less than 40 subs and earning less than $200?

Back

Front

What inequality describes Josie's goal to earn at least $300 selling cake pops (x) for $2 each and brownies (y) for $3 each?

Back

Front

What does a solid line indicate when graphing an inequality?

Back

A solid line indicates that the points on the line are included in the solution (used with ≤ or ≥).

Front

What is the difference between a strict inequality and a non-strict inequality?

Back

A strict inequality (< or >) does not include the boundary, while a non-strict inequality (≤ or ≥) does.

Front

How do you determine if a point is a solution to an inequality?

Back

Substitute the point's coordinates into the inequality and check if the statement is true.

Front

What is the graphical representation of the solution set for a linear inequality?

Back

The solution set is represented by a shaded region on one side of the boundary line.

Front

What is the significance of the boundary line in graphing inequalities?

Back

The boundary line separates the solution set from the non-solution set.
