In the formula "y=mx+b" what is "b"? I've never quite been able to figure that out. :oops:

Mathematically: That is the value of 'y' when x = 0. Geometrically: That is the height of the point on y-axis (from the origin) - where the straight line intersects the y-axis. It is generally referred to as the "y-intercept" of the line.
