Systems of Inequalities

Front

If the inequality symbol is > or \ge, you shade ________.

Back

above

Front

Match the inequalities: y < x−2, y < 3, y > -x+2. Which pairs match?

Back

y < -x+2 and y > 3

Front

Which point is a solution to the system of inequalities? (1, 2), (4, 3), (0, 6), (-2, -5)

Back

(4, 3)

Front

Which point below is NOT part of the solution set? (0, 0), (5, 1), (-1, -3), (20, -5)

Back

(-1, -3)

Front

Identify the system of inequalities shown: y ≥ -x - 1, y < x + 4

Back

y > -x - 1 and y ≥ x + 4

Front

What does the solution set of a system of inequalities represent?

Back

The set of all points that satisfy all inequalities in the system.

Front

How do you graph the inequality y < 2?

Back

Draw a dashed line at y = 2 and shade below the line.

Front

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates that points on the line are included (\ge or \le), while a dashed line indicates they are not included (> or <).

Front

What is the solution to the inequality 2x + 3 < 7?

Back

x < 2.

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, it is a solution.
