Answer NumberLine Questions

WebAssign NumberLine™ 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.
