Question
How many solutions are there when the graphs of linear equations in two variables are coincident?
- Unique solutions
- No solution
- Infinite solutions
- None of the above
Hint:
no of solution is same as common points two lines should have .
The correct answer is: Infinite solutions
If two lines are coincident , means they are same actually , so they have all points common .
So , there exists infinity number of solutions .
