Question

Do the lines of equatiohs 2 x + y -4 = 0 and x + 2y - 5 = O intersect ? Justify your answer.

Answer 1

Hey Mate!!!!!

ax + by +c=0. dx + ey +z=0


Two straight lines intersect each other if


a / b is not equal to d / e



so


2 / 1 is not equal to 1/2

so, the two straight line will intersect each other.
