Back

solid

Front

What is the solution set for the inequality y < \frac{1}{2}x - 1?

Back

The area below the line y = \frac{1}{2}x - 1, not including the line.

Front

What is the solution set for the inequality y \ge -3x + 4?

Back

The area above the line y = -3x + 4, including the line.

Front

What does the symbol \ge mean in an inequality?

Back

It means 'greater than or equal to'.

Front

What does the symbol \le mean in an inequality?

Back

It means 'less than or equal to'.

Front

How do you graph the inequality y < 2x + 3?

Back

Graph the line y = 2x + 3 as a dotted line and shade below it.

Front

How do you graph the inequality y \ge -x + 1?

Back

Graph the line y = -x + 1 as a solid line and shade above it.

Front

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

Back

A solid line indicates that points on the line are included in the solution, while a dotted line indicates they are not.
