Front

When graphing the inequality with < or >, what type of line is used?

Back

Dashed line.

Front

When graphing the inequality with \le or \ge, what type of line is used?

Back

Solid line.

Front

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

Back

(5, 5) is NOT part of the solution set.

Front

Which point is NOT part of the solution set for the inequality y \ge -x + 2? (0, 0), (-10, -10), (-1, 5), (5, 20)

Back

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

Front

What is the solution set of the inequality y < 3?

Back

All points below the horizontal line y = 3.

Front

What is the solution set of the inequality y \ge 2x - 1?

Back

All points on or above the line y = 2x - 1.

Front

How do you determine if a point is part of the solution set for an inequality?

Back

Substitute the point into the inequality and check if it holds true.

Front

What does it mean if a line is dashed in a graph of an inequality?

Back

The points on the dashed line are NOT included in the solution set.
