Graphing Linear Inequalities

Front

What does the symbol < represent in graphing linear inequalities?

Back

It indicates that the solution set includes values below the line.

Front

What does the symbol \le represent in graphing linear inequalities?

Back

It indicates that the solution set includes values below the line, including the line itself.

Front

When graphing the inequality y \ge mx + b, what type of line is used?

Back

A solid line is used because the inequality includes equality.

Front

When graphing the inequality y < mx + b, what type of line is used?

Back

A dashed line is used because the inequality does not include equality.

Front

Which of the following points is NOT part of the solution set for the inequality y < 2x + 3? (0, 0), (-10, -10), (-1, 5), (5, 20)

Back

(-10, -10) is NOT part of the solution set.

Front

What is the correct inequality for the graph that has a solid line with a slope of 2 and a y-intercept of 1?

Back

y \ge \frac{2}{5}x + 1.

Front

What does the symbol > represent in graphing linear inequalities?

Back

It indicates that the solution set includes values above 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 in the solution set, while a dashed line indicates they are not.

Front

If the inequality is y \le -\frac{2}{5}x + 1, how would you shade the graph?

Back

Shade below the line.

Front

What is the solution set for the inequality y > 3?

Back

The solution set includes all points above the line y = 3.
