  1. the constant of variation,  k= 5/7

    Step-by-step explanation:

    if m varies directly as p, and m=5 when p=7, what is the constant of variation

    m varies directly as p, so equation becomes

    m = kp , where k is the constant of proportionality

    m=5 when p=7, we need to find out k

    Plug in the given values and find out k

    m=k * p

    5= k * 7

    Divide by 7 on both sides

    so k= 5/7

  2. For direct relations, we can write:
    m = kp; k is the constant of proportionality.
    5 = 7k
    k = 5/7
    The constant of variation is 5/7.
