Match an inequality to its number line graph

1. A number line runs from 0 to 8. The graph shows an open circle at 2 with the shaded part going toward the smaller numbers. Which inequality does the graph show? Write it using a.

   Answer: a < 2

2. A number line runs from 0 to 8. The graph shows an open circle at 2 and a shaded arrow pointing to the left. Which inequality does the graph show? Write it using w.

   Answer: w < 2

3. A number line runs from 0 to 9. The graph shows a ray that starts at an open circle at 4 and points left. Which inequality does the graph show? Write it using x.

   Answer: x < 4

Tip: Read the circle and the arrow. An open circle means > or <. A closed circle means ≥ or ≤. Right means greater, left means less.
