6. What are some important things
to note about this graph when
compared to the inequality?
The boundary line is solid.
7. What are some important things
to note about this graph when
compared to the inequality?
The boundary line is solid.
The shading is below the line.
9. Which inequality symbol is used for the
corresponding inequality to this graph?
≤, ≥, >, <
The shading is below the line so y will be
less than
- And -
The boundary line is dotted so it does NOT
include the equals mark.

corresponding inequality to this graph?
≤, ≥, >, <
The shading is above the line so y will be
greater than
- And -
The boundary line is solid so it does
include the equals mark.
