Which system of equations below has exactly one solution?

y = –8x – 6 and y = –8x + 6

y = –8x – 6 and One-halfy = –4x – 3

y = –8x – 6 and y = 8x – 6

y = –8x – 6 and –y = 8x + 6

The given system of equations   and has exactly one solution

Step-by-step explanation:

Given that the system of equations and

has exactly one solution

For :Now to show that the given system of equations has exactly one solution :Solving the given equations (1) and (2) to get solutionAdding the equations (1) and (2) we get

______________

Therefore the value of is y=-6Substitute the value of y in equation (1) we have

Therefore the value of x is x=0

Therefore it has exactly one solution is (0,-6)Therefore the  given system of equations   and has exactly one solutione given  system of equations has exactly one solution
