Graphing Rules

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

• It has just an equal sign.

• The symbol is greater than.

• The symbol has "or equal to."

• You just guess.

y < x - 2 will be shaded

• above

• below

y < 6x + 1 will have what kind of line?

• dashed

• solid

x ≥ 2 will have what type of line?

• dashed

• solid

x ≥ 2 will be shaded

• above

• below

y ≥ 5 will be shaded

• above

• below

Is this graph shaded above or below?

• above

• below

Is this graph shaded above or below?

• above

• below

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.

• The line would be dashed with shading below.

y ≥ -2x - 2 will have what type of line

• dashed

• solid
