If a point P on the line 3 x+5 y=15 is equidistant from the coordinate axes, then P lies
Options
- Aonly in the first quadrant
- Beither in first or in second quadrant
- Ceither in first or in third quadrant
- Donly in the third quadrant
Correct answer
B. either in first or in second quadrant
Step-by-step solution
Let the point P(h, k) lie on the line 3 x+5 y=15 Distance from coordinate axes are equal from P . |h|=|k| h= k Point P line of 3 x+5 y=153 h+5 k=15 3 h+5 h=15 h=15 / 8 k=15 / 8 Put k=-h , 3 h-5 h=15=h= -15 2 , k= 15 2 ( 15 8 , 15 8 ) lie in first quadrant and ( -15 2 , 15 2 ) ie in second quadrant. P lies in the first or in second quadrant.
