Question

निम्न बिन्दुओं A एवं B में भुज व कोटि का निर्धारण कीजिए
(i) A(-3,5)
(ii) B(4,-1)​

Answer 1

Given : बिन्दु  A एवं B   Point A and B

(i) A(-3,5)

(ii) B(4,-1)​

To Find : भुज व कोटि

Abscissa and ordinate

Solution

 भुज  (abscissa)

कोटि (ordinate)

भुज  (abscissa) किसी बिंदु की y-अक्ष से दुरी को x-निर्देशांक अथवा भुज कहते हैं।

कोटि (ordinate) - किसी बिंदु की x-अक्ष से दुरी को y-निर्देशांक अथवा कोटि कहते हैं।

किसी बिंदु के भुज और कोटि (x, y) के रूप में होते हैं।

abscissa the distance from a point to the vertical or y -axis, measured parallel to the horizontal or x -axis; the x -coordinate.

ordinate  the distance from a point to the horizontal or x-axis, measured parallel to the vertical or y -axis; the y -coordinate.

(i) A(-3,5)    Abscissa  -3  , ordinate 5    भुज  = -3  और कोटि  - 5

(ii) B(4,-1)​     Abscissa 4  , ordinate -1    भुज  =4  और कोटि  -1

Answer 2

SOLUTION

TO DETERMINE

The abscissa and ordinate for the points A and B

(i) A(-3,5)

(ii) B(4,-1)

CONCEPT TO BE IMPLEMENTED

For any point (a, b) in Cartesian Coordinate system

Abscissa

= Distance of the point from y axis = a

Ordinate

= Distance of the point from x axis = b

EVALUATION

(i) Here the given point is A(-3,5)

Abscissa

= Distance of the point from y axis = - 3

Ordinate

= Distance of the point from x axis = 5

(ii) Here the given point is B(4,-1)

Abscissa

= Distance of the point from y axis = 4

Ordinate

= Distance of the point from x axis = - 1
