You can put this solution on YOUR website! Rewrite 14x-7y=21 so that y is a function of x. The statement "y is a function of x" means to write y with respects to x or better said to isolate y as it equals x on the other side of the equation.
 To do so, we first subtract -14x from both sides.
 Doing so, we now have this equation:
 -7y = -14x + 21
 To finally write y as a function of x, we divide both sides of the equation by -7.
 y = (-14x + 21)/-7
 y = 2x - 3
 Easy, right?
