The point at which these two number lines intersect each other is known as the point of intersection which is also known as the origin. It is denoted by the letter O, which is used as a fixed point of reference for the geometry of the surrounding plane. The coordinates of the origin are denoted by (0, 0). It means that at origin, x=0 and y=0.
A point on the real number line that is associated with a coordinate is called its graph. To construct a number line, draw a horizontal line with arrows on both ends to indicate that it continues without bound. Next, choose any point to represent the number zero; this point is called the origin. Figure 1.1.2 1.1. 2.
Example 1: Compare – 25 and 15 using a number line. Solution: Let’s locate –25 and 15 on the number line. Since, – 25 is to the left of 15 , – 25 < 15 . Example 2: Add – 7 + 7. Solution: Let’s locate –7 on the number line and move 7 steps to the right to find the answer. So, – 7 + 7 = 0.
Determine the distance of the point -10 from the origin on a number line. Solution. The position -10 from the origin, or 0 on a number line, is 10 units away. Example 2. Calculate the separation between points (0, -7) and the origin. Solution. The distance of (0, -7) from (0, 0)=-7=7 units. Example 3. Where does the Cartesian Plane come from ...
Jan 14, 2024 · A number line is a straight line with numbers placed at equal distances on it, symbolizing the real number system. The number line’s origin is the point where the value is zero, which segregates the positive numbers on the right and the negative numbers on the left. The origin, in this context, acts as a keystone that enables the measurement ...

Definition. As the name suggests, a number line is a visual representation of numbers on a line that can be drawn as an x-axis or y-axis. The line compares numbers that are equally spaced on an infinite line extending both horizontally and vertically, with equal intervals. 00:00. 00:00.
