3.8 Formative - System of Inequalities Review

Front

An inequality using a > or a < has a ___________ line.

Back

dashed

Front

Which point is a solution to the system of inequalities? (0, 6), (-3, 4), (1, 0), (-4, 3)

Back

(1, 0)

Front

Which of the following is not a solution to this system of inequalities? (0,-1), (0,3), (4,0), (6,-2)

Back

(0,-1)

Front

What does a solid line represent in an inequality?

Back

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

Front

What does a dashed line represent in an inequality?

Back

A dashed line indicates that the points on the line are not included in the solution set (> or <).

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality; if it satisfies all inequalities, it is a solution.

Front

What is the graphical representation of a system of inequalities?

Back

The solution is the overlapping region of the graphs of the inequalities.

Front

What is the first step in solving a system of inequalities by graphing?

Back

Graph each inequality on the same coordinate plane.

Front

What is the significance of the shaded region in a graph of inequalities?

Back

The shaded region represents all the possible solutions to the inequalities.

Front

If a system of inequalities has no overlapping region, what does that mean?

Back

It means there is no solution to the system.
