Exactly. This method returns the rest of the current line, excluding any line separator at the end. The problem is that nextline, unlike nextint or nextbool, expects no particular value, it is perfectly happy with an empty string. Being no real java programmer, I only guess you could close/open a n...

Ah okay, so as long as within a given line they don't change no matter what the point values, but not if it's a completely different line, m and b are still considered constants. That makes sense I guess.
