(A)
Explanation:
This system of equations will no solution if they have the same slope and only differ in the y-intercept values. So let's rewrite the two equations into their slope-intercept forms:


For them to have no solution, their slopes must equal each other:

or

Putting this value into our system of equations, we get


This is a system of equations consisting of two parallel lines and as such, do not intersect and so, no solution.
