    Answer:

    Let A(2,k) and B(-4,2) be two points and slope m=1/2

    Slope=y2-y1/x2-x1

    1/2=2-k/-4-2  [y1=k,y2=2,x1=2,x2=-4,m=1/2]

    -(4+2)=2(2-k)

    -6=4-2k

    2k=10

    ⇒k=5

    Hope it helps you.

    Answer:

    k = 5

    Step-by-step explanation:

    The slope can be found by using the formula:

    Slope =( Y₂-Y₁ )/ ( X₂-X₁ )

    Therefore,

    1/2 = (2 – k) / (-4 -2)

    1/2 × -6 = 2 – k

    -3 – 2 = – k

    -5 = -k

    5 = k

    So k = 5
