    No the answer is 70 because do seven times o and then you know that 0 so but the zero at the end and do seven times one and get seven so you know it no 80 so the number it is close to is 70

    Step-by-step explanation:

    subtract 10x from both sides to get 7y = - 10x + 80

    Divide both sides by 7

    y = - 10/7x + 80/7
