How does the position of a point on the number line relate to its value?

Answer 1

Gabriel Agustin

Please see below.

(1) If the number is to the right of #0#, it is positive.

(2) If the number is to the left of #0#, it is negative.

(3) If there are two numbers on the line, the one on the left is smaller than one on the right.

(4) We can also say that a number on the right is larger than the one to the left of it.

The position of a point on the number line corresponds to its numerical value. Points to the right represent numbers greater than zero, with larger values positioned farther to the right. Conversely, points to the left represent negative numbers, with larger negative values located farther to the left. The distance between two points on the number line reflects the numerical difference between their corresponding values.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
