8. If a=5, the point b=7, c= 3 and d=-5, then (a) is in the quadrant.
A. Second B. First C. third D. fourth
9. If (a, b) and (b, a) represent the same point in the coordinate plane, then....... is possible.​

Answer 1

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
