Question 123928: Here is the question:
The only value of m for which the following system does not have a unique solution is: m = _______.
s + mx = -7
-7s - 2x = -2
Moreover, for this value of m the system of equations:
a. has infinitely many solutions
b. is inconsistent
I've tried to work this problem out but I can't figure it out.
Thanks! Answer by solver91311(24713) (Show Source):
In order for there to be no unique solution, the slopes of the two lines must
be identical, that is . Since the intercept values are different,
the system is inconsistent, that is these are parallel lines that do not intersect.
