Question -
Answer -
(A) parallel (B)intersecting at (b, a)
(C) coincident (D)intersecting at (a, b)
Solution:
(D) intersecting at (a,b)
Explanation:
Graphically in everycondition,
a, b>>0
a, b< 0
a>0, b< 0
a<0, b>0 but a =bтЙа 0.
The pair of equationsx = a and y = b graphically represents lines which are intersecting
at (a, b).
Hence, the cases twolines intersect at (a, b).
