    Answer:

    • k = -16

    Step-by-step explanation:

    Given formula:

    • 4y= -kx – 2, where slope is 4

    Slope-intercept formula is:

    • y = mx + b, where m is the slope

    Finding slope by bringing the formula to the same format as above:

    • 4y = -kx – 2
    • y = -k/4x – 1/2

    Slope is -k/4 and comparing it with the given:

    • -k/4 = 4
    • k = 4*(-4) = -16
