Question 164

There are two straight lines in the x-y plane with equations:

ax + by = c

dx + ey = f

Do the two straight lines intersect?

A. a, b, c, d, e and f are distinct real numbers.

B. c and f are non-zero.


Using option B we know that since the constant terms are non-zero and unique , the lines do not intersect at the origin. Also since other coefficients are not equal , the lines can be parallel or intersecting . Hence, the question cannot be answered even by using both statements together.
