So from about this point in time to, let's say about this point in time, the curve looks like a straight line. And in fact, this equation also describes an equation that looks like a straight line. So remember, a straight line has the following general form. So y, the Y coordinate is equal to and the slope multiplied by x the x coordinate plus b the y intercept. Now B in this particular case is zero. So this is zero and it cancels out.
