Point p(-3, 5) lies in __________ quadrant.(a) 1^st(b) 2^nd(c) 3^rd(d) 4^thThis question was addressed to me during an interview.Asked question is from Plotting a Point in the Plane if its Coordinates are Given in section Coordinate Geometry of Mathematics – Class 9

Answer»

Correct option is (b) 2^nd

For EXPLANATION: As shown in the diagram below, p(-3, 5) means that its x-coordinate is -3 and y-coordinate is 5. Therefore point’s distance from y-AXIS will be 3 in negative direction (Along XX’ axis) and its distance from x-axis will be 5 in POSITIVE direction (along OY axis).

Considering this, we can locate the point p(-3, 5) as shown in diagram which lies in 2^nd quadrant.

OR

Short TRICK: We can see that p(-3, 5) is of (-, +) form. We KNOW that any point of (-, +) form lies in 2^nd quadrant.
