Systems of Inequalities

• dashed
• solid
• wavy
• imaginary

Which of the following inequalities will have a dashed line and which will have a solid line?

Groups:

(a) Dashed Line

,

(b) Solid Line

When ​ (a)   or ​ dividing by a ​ (b)   number you have to ​ (c)   the inequality symbol.

• multiplying
• negative
• flip
• adding
• subtracting
• positive
• keep

Select the region of the graph that is a solution to BOTH inequalities.

Select the region of the graph that does NOT have solutions to either of the inequalities.

For which of these equations do you shade above the line and which do you shade below the line?

(HINT - there is an equal amount of each)

Groups:

(a) Above

,

(b) Below

When graphing inequalities, always put your equation in ​ (a)   form.

• y = mx+b
• Ax + By = C
• slope
• point-slope
