Ian Pulizzotto. 5 years ago. The forms y=mx+b and y=mx+a are essentially the same, except for the naming of the constant term. The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m (x-a) is essentially different from the other two forms, and means slope m and x-intercept ...
