SOLUTION
TO CHOOSE THE CORRECT OPTION
If x and y are both positive solution of equation ax + by + c = 0 , always lie in
a) first quadrant
b) second quadrant
c) third questions
d) fourth quadrant
EVALUATION
We know that in two dimensional geometry the Cartesian plane is divided by coordinate axis in 4 quadrant
1. Quadrant I : Both the x - coordinates and y - coordinates are positive
2. Quadrant II : The x - coordinate is negative and the y - coordinate is positive
3. Quadrant III : Both the x - coordinates and y - coordinates are negative
4. Quadrant IV : The x - coordinate is positive and the y - coordinate is negative
EVALUATION
Here It is given that x and y are both positive solution of equation ax + by + c = 0
This gives ,
The x - coordinates is positive
The y - coordinates is positive
Since Both the x - coordinates and y - coordinates are positive
So the point lies in first quadrant
FINAL ANSWER
Hence the correct option is a) first quadrant
