If a point is in 2^nd quadrant, then it is in __________ form.(a) (+, +)(b) (+, -)(c) (-, +)(d) (-, -)I got this question by my college professor while I was bunking the class.I would like to ask this question from Coordinate Geometry & Cartesian System topic in chapter Coordinate Geometry of Mathematics – Class 9

Answer»

Correct choice is (c) (-, +)

The explanation is: As SHOWN in diagram below, any POINT in 2^nd QUADRANT will be in the FORM (-, +) since 2nd quadrant is enclosed by negative x – axis and POSITIVE y – axis.

Similarly, any point in 1^st quadrant will be in the form (+, +).

Any point in 3^rd quadrant will be in the form (-, -).

Any point in 4^th quadrant will be in the form (+, -).
