on a horizontal number line, negative numbers are located on which side of $0$.
A.Right
B.Left
C.Above
D.Below

Hint: we will first draw a number line and mark the points. Check the points in the number line and take $0$ as you see in which hand side the negative numbers lie there you will find the answer.

Complete step-by-step answer:
In math, a number line can be defined as a straight line with numbers placed at equal intervals or segments along its length. A number line can be extended infinitely in any direction and is usually represented horizontally.
First draw a number line like the below diagram,

Let us suppose that at point $0$ you are standing and now see in the line diagram,
Initially, you take your hands and see on which hand side the negative value lies then, we can observe that the negative values lie on the left hand side.
So it is clear that the negative values lie on the left side of zero and the positive values lies in the right side of zero.
So, the correct answer is “Option B”.

Note: In this problem, point zero plays an important part. We don’t need to turn the number line in any direction, just keep the number line diagram in front of you and see in which hand the negative points lie. That will be the correct answer.
