Equation of line passing through the point  a,b,cand making equal angles with coordinate axes where  a,b,care all positive 

a
x−a=y−b=z−c
b
x−aa=y−bb=zc
c
x−a1=y−b2=z+c1
d
x+a=y+b=z+c

detailed solution

Correct option is A

If a line makes equal angles with coordinate axes, then the direction ratios of that line are proportional to1,1,1Hence, the equation of the line passing through the point  a,b,cand having direction ratios  1,1,1isx−a=y−b=z−c
