Practice Number Line in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

A straight line where each point represents a number, with equal spacing giving a visual model of all real numbers. The number line extends infinitely in both directions, with negative numbers to the left of zero and positive numbers to the right, providing a geometric representation of order and distance.

Numbers live in order on a line—smaller to the left, larger to the right.

Example 1

easy
Plot and label the following on a number line: -3, -\dfrac{1}{2}, 0, 1.75, \dfrac{7}{3}. Then find the distance between -3 and \dfrac{7}{3}.

Example 2

medium
Find all integers within distance 2.5 of -1 on the number line.

Example 3

medium
On a number line, point A is at -3 and point B is at 5. Find the midpoint and the distance between them.

Example 4

easy
On a number line, point A is at -4 and point B is at 6. Find the midpoint of AB and the distance AB.

Example 5

medium
A frog starts at 0 on a number line. It jumps +5, then -3, then +7, then -9. Where does it land, and what is the total distance travelled?
