Q13 of 34 Page 1

For what values of p does the pair of equations 4x + py + 8 = 0 and 2x + 2y + 2 = 0 has unique solution?

OR


What type of straight lines will be represented by the system of equations 2x + 3y = 5 and 4x + 6y = 7?


is the condition for the given pair of equations to have unique solution.



p ≠ 4


Therefore, for all real values of p except 4, the given pair of equations will have a unique solution.


OR


Here,




is the condition for which the given system of equations


will represent parallel lines.


So, the given system of linear equations will represent a pair of parallel


lines.
