Question

7.In which quadrant or on which axis each of the given points lies:
a) (1,-7)​

Answer 1

Step-by-step explanation:

(ii) Points (1, –1) and (–1, 1) lie in the same quadrant. (iv) A point lies on y-axis at a distance of 2 units from the x-axis. Its coordinates are (2, 0). (v) (–1, 7) is a point in the II quadrant.

Answer 2

Answer:

(i) 3,−4  

absicca  =3            ordinate =−4

since absicca is possitive and ordinate negative , it lies in 4th quadrant  

(ii) −3,5

absicca  =3            ordinate =5

since absicca is negative and ordinate is positive, it lies in 2nd quadrant  

(iii) −10.0

absicca =−10        ordinate  =0

since the ordinate is 0, this point lies on the x−axis

(iv) −2,−7

absicca =−2    ordinate =−7

since absicca and ordinate , both are negative, this point lies in 4th quadrant
