Question

The horizontal axis is called ____ axis
A) y - axis
B) x - axis
C) Ambiguous
D) Data insufficient

Answer 1

Hint: The axes are used in a Cartesian plane, we can understand what the axes are, what are the other parts of the Cartesian plane and then come to conclusion about what the horizontal axis is called as.

Complete step by step solution:
We define the position of a point or an object using the Cartesian plane by the help of two intersecting lines, one horizontal and one vertical.
These two intersecting lines are known as axes in plural and axis in singular. The line that is horizontally placed is called x – axis and the line that is vertically placed is called y – axis.
When we define the position of any point in the coordinate system, it is done as (x, y) representing the horizontal and vertical distances from the respective axes.
The intersecting point is known as the origin (O), the regions formed are called quadrants. The left side of x – axis is negative while below the origin is negative y – axis.
The Cartesian plane along with the axes is shown as:

Therefore, it can be concluded that the horizontal axis is called x – axis
So, the correct answer is “x – axis ”.

Note: The x and y axes are also called as abscissa and ordinate respectively. But, as they were not given in the options, we did not consider them and stick to the axes.
When the position is described as (x, y) with respect to the x and y axes, this pair is known as the ordered pair.
The Cartesian plane can be 1, 2 or 3 dimensional, the axes remain the same. But, in 3 dimensional a third axis called z – axis is added.
