Question

*Fill in the blank: On solving the linear pair of equation by graphical method, if the lines so obtained are parallel, then there will be __________.*

1️⃣ only one solution
2️⃣ infinitely many solution
3️⃣ no solution
​

Answer 1

On solving the linear pair of equation by graphical method, if the lines so obtained are parallel, then there will be no solution.

➡️no solution

Answer 2

On solving the linear pair of equation by graphical method, if the lines so obtained are parallel, then there will be no solution (option 3)

• Since the parallel lines will never meet at a any given point, there will be no solution of the pair of linear solution.
• If the lines are coinciding, there will be infinitely many solutions.
• If the lines obtained by the graph, intersect at a point, they will have a unique solution.
