Graphing Linear Inequalities in Standard Form

What does a solid line in an inequality graph represent?

• The inequality includes equal to (≥ or ≤).

• The inequality does not include equal to (> or <).

• The inequality is only greater than (>).

• The inequality is only less than (<).

When graphing 'greater than' inequalities, in which direction should the area be shaded?

• No shading is required

• Shading is optional

• Upwards

• Downwards

What is the first step in converting a standard form inequality to slope-intercept form?

• Subtract the x-term from both sides

• Multiply all terms by the coefficient of y

• Add the x-term to both sides

• Divide all terms by the coefficient of y

After subtracting 2x from both sides, what is the inequality form?

• y ≥ -2x - 9

• 3y ≥ -2x - 9

• 3y > -2x - 9

• 3y = -2x - 9

What is the slope of the line y ≥ -2/3x - 3?

• -2/3

• 3

• 2/3

• -3

In the inequality y > -3x + 5, what is the y-intercept?

• 3

• 5

• -3

• -5

What type of line is used when the inequality does not include 'or equal to'?

• No line

• Thick line

• Dotted line

• Solid line

If an inequality is divided by a negative number, what must be done to the inequality sign?

• It becomes an equals sign

• It is removed from the equation

• It must be reversed

• It remains the same

What is the slope of the line described by the inequality y < 1/4x + 4?

• -4

• 4

• 1/4

• -1/4

What does shading downwards in an inequality graph indicate?

• The line is solid.

• The variable y is greater than the expression on the right.

• The variable y is less than the expression on the right.

• The line is dotted.
