I don't understand the meaning of the problem. If y=c then x=0. Enlighten me, please.
If y=mx+b, when y=c, x=?
Dan: in my mathematical understanding (correct me if I am wrong): if y=c the slope m of the curve is 0. but for all x the condition y = c is correct, so x should be infinite
Or is there some error in the solution?
The problem description needs to be improved, maybe to something like: Given two points in a Cartesian coordinate system, find the x-value on the line y = a*x+b in which the y-value is equal to a given value c.
The description has been updated.
Nice one. hard to figure this out.
I don't like my solution. I rader prefer David's. JEJE
nice solution :-)
