Linear Inequalities in two variables

Front

What type of line is used with the symbols < and >?

Back

Dashed or dotted line.

Front

What type of line is used with the symbols ≤ and ≥?

Back

Solid line.

Front

Which inequality represents a graph with a solid line and shading above?

Back

y ≥ -3/4 x + 3.

Front

What does the inequality y < 2x + 3 indicate about the line and shading?

Back

The line would be dashed with shading below.

Front

Which point is NOT part of the solution set for the inequality y ≥ -3/4 x + 3?

Back

(-1, -3).

Front

What is a linear inequality in two variables?

Back

An inequality that can be written in the form ax + by <, >, ≤, or ≥ c.

Front

How do you graph a linear inequality?

Back

1. Graph the boundary line. 2. Use a dashed line for < or >, and a solid line for ≤ or ≥. 3. Shade the appropriate region.

Front

What does the solution set of a linear inequality represent?

Back

All the points (x, y) that satisfy the inequality.

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 (≤ or ≥), while a dashed line indicates they are not included (< or >).

Front

If the inequality is y < 2x + 3, where would the shading be?

Back

Below the line.
