Question

Define axis.

Answer 1

Hint:Here in this question we have to define the axis, since they have mentioned only axis. So we explain about both two dimensional axes and three dimensional axes. By giving the figure or diagram of the axes we get a clear picture. Hence we obtain a required answer to the given question.

Complete answer:
Usually, the plane figures are plotted by using axes. Especially we plot a graph on the axis.An axis is an imaginary line that passes through the origin point of a geometric coordinate system. Each dimension of the system has exactly one axis. For every point on an axis, the value of every other dimensional coordinate is zero. The axis is represented as

The two lines which meet perpendicularly at point O. The horizontal line is called the $x$ axis and the vertical line is called the $y$ axis. In this axis we have four quadrants. XOY is the first quadrant, X’OY is the second quadrant, X’OY’ is the third quadrant and XOY’ is the fourth quadrant.

The four quadrants is represented as given below:

This is a two dimensional, three dimensional axis. In a three dimensional axis there is a three lines which are perpendicular to each other. The three dimensional axis is represented as

For the three dimensional there is a negative value also.

Note:In an axis there are negative and positive numbers which are integers and its range will be from \[ - \infty \] to \[ + \infty \] in both directions. The abscissa refers to the horizontal (x) axis and the ordinate refers to the vertical (y) axis of a standard two-dimensional graph. The intersecting point will be zero.
