1)

The equation of liner equality inclined to coordinate axes and passing through (-3,2,-5) is 


A) x+31=y21=z+51

B) x+31=y21=z+51

C) x+31=y21=z+51

D) x+31=2y1=z+51

Answer:

Option B

Explanation:

Let (x1,y1,z1) =(-3,2,-5)

It is also given that, the line is equally inclined to coordinate axes,

     l=-1,m=1 and n=-1

 We know that , the equation of line passing through (x1,y1,z1) and having cosines l,m, n is 

xx1l=yy1m=zz1n

      x+31,y21,z+51
