Combining number lines. A line drawn through the origin at right angles to the real number line can be used to represent the imaginary numbers. This line, called imaginary line, extends the number line to a complex number plane, with points representing complex numbers.
A blank number line is a visual diagram with no numbers or markers and is essentially used as a tool for solving word problems. Let us practice number line examples to understand it even better. Solved Examples on Number Line. Example 1: Compare $–25$ and $15$ using a number line. Solution: Let’s locate –25 and 15 on the number line.

Zero (0) is considered to be the origin of a number line. The numbers to the left of 0 are negative numbers and the numbers to the right of 0 are all positive numbers. So, we can say that on a number line, as we move towards the right, the value of numbers increases.
Any real number can be associated with a point on a line. Create a number line by first identifying the origin and marking off a scale appropriate for the given problem. Negative numbers lie to the left of the origin and positive numbers lie to the right. Smaller numbers always lie to the left of larger numbers on the number line.
History. A number line is an abstract notion which evolved early 20th century. A number line should be distinguished from the solid and geometrical line. A solid number line or an interval is an image that came into existence in the ancient world. As a notion, a geometrical line or axis formed by analysis in the period of time in 16th to 18th ...
Aug 3, 2023 · A number line is a visual representation showing how numbers are arranged on a horizontal straight line. The arrangement is such that a number to its left is always less than a number to its right. In another way, the numbers on the right are always less than those on the left. Number Line. Find where are 9 and (-5) on the given number line.
If you get y = 0, then the line of the equation will pass through the origin. Solved Examples. Example 1: Find the distance of the point from the origin on a number line. Solution: The distance of the point -10 from the origin, i.e., 0 on a number line =10 units. 2. Find the distance of the point (0, -7) from the origin.
