Well we know that this right over here, dy dx, this is m. This is m. And it's equal to two. So we could say that two is equal to two x minus y. Two is equal to two x minus y. And let's see, if we solve for y, add y to both sides, subtract two from both sides, we get y is equal to two x minus two. And there we have our whole solution. And so you have your m right over there. That is m. And then we also have our b.
