No, you're not off track. The only way there are infinite solutions for real values of are when , and the only way there are no solutions are when
I can't see any way to find real values of m that give 'just one solution'.
I have been asked to find real values for m such that this system of equations has no solution, infinitely many solutions and exactly one solution:
At first I thought that the question wanted me to find a value for each scenario, but I could only find a value that gave infinitely many solutions: m = 25. I can see that they are essentially the same line so any value other than 25 would just shift it up or down and cause the two lines to never intersect.
I couldn't see any other real value for m could produce any solutions until I though what if m = 10y ?
(sub into first equation)
Am I way off track with this question?
Does that count? I guess there would be infinitely many ways to do that though...
