Question

In the Cartesian plane, the vertical line is called Y-axis.
(A)True
(B) False

Answer 1

Hint: In this question, we have to find out the given statement is true or false. We need to first find out the definition of the Cartesian plane. By analysing the definition to our requirement we will get the correct answer. So that we can find out the given particular.

Complete step-by-step solution:
It is given that in the Cartesian plane, the vertical line is called Y-axis.
We need to find out the given statement is true or false.
A Cartesian coordinate system in two dimensions (also called a rectangular coordinate system or an orthogonal coordinate system) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes, and an orientation for each axis.
A Cartesian plane (named after French mathematician Rene Descartes, who formalized its use in mathematics) is defined by two perpendicular number lines: the x-axis, which is horizontal, and the y-axis, which is vertical. Using these axes, we can describe any point in the plane using an ordered pair of numbers.
The location of a point in the plane is given by its coordinates, a pair of numbers enclosed in parentheses: \[\left( {x,y} \right)\]. The first number x gives the point's horizontal position and the second number y gives its vertical position.
$\therefore $ Option (A) is the correct option.

Note: We have to know that a Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a set of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.
