Question

Solve a pair of linear equation
by graphical method​

Answer 1

Answer:

Let the system of pair of linear equations be

a1x + b1y = c1 ….(1)

a2x + b2y = c2 ….(2)

We know that given two lines in a plane, only one of the following three possibilities can happen –

(i) The two lines will intersect at one point.

(ii) The two lines will not intersect, however far they are extended, i.e., they are parallel.

(iii) The two lines are coincident lines.
