Graphing Linear Inequalities Concepts

What is a system of linear inequalities?

• A set of linear equations

• A quadratic equation

• Two or more linear inequalities graphed together

• A single linear inequality

In the equation y = -x - 1, what is the slope?

• -1/1

• 1/1

• -1

• 1

When graphing y = -x - 1, why is the line dashed?

• Because it is a horizontal line

• Because there is no equal sign in the inequality

• Because it is a vertical line

• Because it is a solid line

For the equation y = x - 5, which direction should you shade?

• To the right of the line

• To the left of the line

• Below the line

• Above the line

In the equation 5x + 2y ≥ 4, what is the y-intercept after rearranging to slope-intercept form?

• 4

• -2

• -4

• 2

Why is the line for the equation 5x + 2y ≥ 4 solid?

• Because it is a vertical line

• Because it is a horizontal line

• Because there is an equal sign in the inequality

• Because it is a dashed line
