You only need two points To draw a linear function. 2 points of reference... From this you can derive the equation y=mx+b And the line goes on forever, never wavering or changing and 2 events can predict the future behavior of the graph When it is linear. I have you and another, I've tried twice 2 events and 2 points. You do not love me, I loved Another took our friendship for more: I feel more. But that does not matter, at the end I was in pain, twice I miscalculated yet I'm good at math, shouldn't I see the pattern now? Now I draw a line on the graph That goes on for infinity.
