Question

How many number lines comprise the basic parts of a cartesian coordinate system?

Answer 1

The correct answer is 2.

Explanation:

The Cartesian coordinate system is made up of 2 axes, the x-axis and the y-axis. 

Each axis is a number line; the x-axis is a number line that runs horizontally across the graph, and the y-axis is a number line that runs vertically along the graph.

Answer 2

Answer:

Step-by-step explanation:

Cartesian coordinate system also known as rectangular system of coordinates has two number lines mutually perpendicular to each other cutting at the origin.

The horizontal line is called the x axis and the vertical line is called the y axis.

The point of intersection is the origin.  The plane is divided into four equal quadrants by these two lines.  I quadrant has both x and y positive, II quadrant has (x,y) as (negative, +ve), III quad (-,-) and IV (+,-)

This enables to graph any two dimensional functions as graphs.
