Suppose that y is directly proportional to x.
a. Use the given information to find the constant of proportionality k.
b. Then use y=kx to find y for x=6
y=-58 when x=7

  • Math - ,

    y = k * x

    When x = 7 then y = - 58


    - 58 = k * 7 Divide both sides with 7

    - 58 / 7 = k


    k = - 58 / 7


    y = k * x


    when x = 6


    y = - 58 * 6 / 7


    x = - 348 / 7
