    once you have M, use this to find the midpoint from (1,7) to M

    this works because the quarter point is exactly half way between the starting point and the midpoint

    so that's the x coordinate of the midpoint between (1,7) and (9.5, 14.5) ie...it's the x coordinate of the quarter point

    so for the y coordinates i would add 7+14.5 which will give me 21.5 and then divide it by 2 which will give me 21.5
