Question

rules of cartesian system​

Answer 1

Answer:

The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes. These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the two coordinates are

I (+,+), II (−,+), III (−,−), and IV (+,−).

Answer 2

Step-by-step explanation:

he number

line, distances from a fixed point are marked in equal units positively in one direction

and negatively in the other. The point from which the distances are marked is called

the origin. We use the number line to represent the numbers by marking points on a

line at equal distances. If one unit distance represents the number ‘1’, then 3 units

distance represents the number ‘3’, ‘0’ being at the origin. The point in the positive

direction at a distance r from the origin represents the number r. The point in the

negative direction at a distance r from the origin represents the number −r
