Front

What does the symbol < represent in inequalities?

Back

It indicates that the value on the left is less than the value on the right.

Front

What does the symbol \le represent in inequalities?

Back

It indicates that the value on the left is less than or equal to the value on the right.

Front

When graphing the inequality y < 5, where do you shade?

Back

Below the line y = 5.

Front

When graphing the inequality y \ge 5, what type of line is used?

Back

A solid line, because the inequality includes equality.

Front

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

Back

A dashed line indicates that the points on the line are not included (strict inequality), while a solid line indicates that the points on the line are included (inclusive inequality).

Front

How do you determine which direction to shade when graphing an inequality?

Back

Shade above the line for inequalities with > or \ge, and shade below the line for < or \le.

Front

What does the inequality y < 3 represent on a graph?

Back

It represents all points below the horizontal line y = 3.

Front

If an inequality is written as y > 2x + 1, where do you shade?

Back

Above the line represented by the equation y = 2x + 1.

Front

What is the solution set of the inequality x \le 4?

Back

All values of x that are less than or equal to 4.

Front

How do you graph the inequality x > 1?

Back

Draw a dashed vertical line at x = 1 and shade to the right.
