    Answer:

    y = 3/7 x

    Step-by-step explanation:

    first we have to replace the value of the following formula with 2 points

    m = (y2 – y1) / (x2 – x1)

    m = (6 – 3) / (14 – 7)

    m = 3 / 7

    Now we are going to replace with the other point, to make sure that the 3 points belong to the function

    y = mx + b

    9 = 3/7 * 21 + b

    9 = 9 + b

    9 – 9 = b

    0 = b

    as b gave us zero it is not necessary to write the sum

    y = 3/7 x
