Answer:
Inconsistent
Note:
If we consider two lines,
ax + by + c = 0
a'x + b'y + c' = 0
Then,
• They are said to be consistent if they intersect or coincide each other.
• They are said to be inconsistent if they are parallel.
• They intersect at a distinct point if ;
a/a' ≠ b/b'
• They coincide each other if ;
a/a' = b/b' = c/c'
• They are parallel if ;
a/a' = b/b' ≠ c/c'
Solution:
The given equations of lines are ;
3x - 6y = 0
x - 2y = 6 or x - 2y - 6 = 0
Clearly , we have ;
a = 3
a' = 1
b = -6
b' = -2
c = 0
c' = -6
Now,
a/a' = 3/1 = 3
b/b' = -6/-2 = 3
c/c' = 0/-6 = 0
Clearly,
a/a' = b/b' ≠ c/c'
Thus,
Both the lines parallel and hence they are inconsistent.
Hence,
The given lines are inconsistent
