Graphing Line for Inequality

How can I tell if an inequality will have a solid line?

• It has an equal sign.
• The symbol is greater than.
• The symbol has "or equal to."
• You just guess.

Consider the function y<2x+3. Which is true?

• The line would be solid with shading above.
• The line would be dashed with shading above.
• The line would be solid with shading below.
• None of these.

Do I need to flip my sign?
2x -3y  ≥ 12

• Yes
• No

Identify the y-intercept for the function:
y=-3x

• -3
• 0
• 1
• -1

Do I need to flip my sign?
3x  ≥ 12

• Yes
• No

Which ordered pair is a solution of the inequality?

y ≥ 4x – 5

• (3, 4)

• (3, 0)

• (2, 1)

• (1, 1)

Which of the following inequalities matches the given graph?

• x ≥ -1
• x ≤ -1
• x > -1
• x < -1

Write the inequality in slope-intercept form:
-10x + 2y > 14

• y < 10x + 12
• y > 10x + 7
• y < 5x + 7
• y > 5x + 7

Write the inequality in slope-intercept form:
5x - y  ≤ 16

• y ≤ 5x + 16 
• y ≤ 5x - 16 
• y ≥ 5x + 16 
• y ≥ 5x - 16
