WebAssignNumberLine™ questions require you either to
draw objects or to place labeled points on a number line.

If needed, high school students can continue to use an older version of the numberline
tool that requires Flash® through Spring 2020.

Most NumberLine questions require you to draw objects to graph
intervals or inequalities. For these questions, all of the NumberLine tools are
available to you.

Some NumberLine questions require you to place labeled points on the
number line. For these questions, a set of labeled points is displayed above the number line and
the drawing tools below the number line are not active.

Plot your answer on the number line or indicate that no solution exists.

Note

Depending on which type of NumberLine question you are answering, some actions will not
be available.

Two objects or points cannot be placed at exactly the same position on the number
line.
