Since the new line we need to make must be parallel to the old one the number changing x must stay the same. this means that that we will still have -⅓ X. Now that we have part of the line formula, we can try to fit it to the point. Because the X is equal to 9, -1/3*9 is -3. To get it to the correct point, we have to add 7, so that our Y is 4. If we combine the two parts of the equation, we get Y=-⅓x+7
