d Statement 1 is false and Statement 2 is true.

Text Solution

Verified by Experts

The line of intersection of the given plane is `3x-6y-2z-15=0= 2x+y-2z-5=0`
For `z=0`, we obtain `x=3 and y=-1`.
`therefore" "` Line passes through `(3, -1, 0)`
Also, the line is parallel to the cross product of normal to given planes, that is
`" "|{:(hati,,hatj,,hatk),(3,,-6,,-2),(2,,1,,-2):}|= 14hati+2hatj+15hatk`
The equation of line is `(x-3)/(14)= (y+1)/(2)= (z)/(15) = t`,
whose parametic form is
`" "x=3+14t, y=-1+2t, z=15t`
Therefore, Statement 1 is false.
However, Statement 2 is true.
