A. (−8, 5)

B. (8, 5)

C. (8, −5)

D. (−8, −5)

Q. Question 1
Point (-3, 5 ) lies in the

A) First quadrant
B) Second quadrant
C) Third quadrant
D) Fourth quadrant

Thinking process
(i) Firstly, check the sign of each coordinate of a point.
(ii) If both coordinates x and y has the same positive sign, i.e(+ .+), then the point lies in the first quadrant.
(iii) If x coordinate has the negative sign and y-coordinate has positive sign i.e( -, +), then the point lies in the second quadrant.
(iv) if both coordinate x and y has negative sign i.e ( -, -) then the point lies in the third quadrant.
(v) if x coordinate has a positive sign and y-coordinate has negative sign i.e (+, -), then the point lies in the fourth quadrant.
