    Seeking name for a formula

    Does this relationship have a name?
    Code:
    x = y + 1
    x^2 - y^2 = x + y

    (shrugs) As y = x - 1 (the second equation adds nothing new) this relationship is merely the line with slope 1 and y-intercept (0, -1).

    Its a consequence of the difference of two squares formula:

    x^2-y^2=(x+y)(x-y)
