    3/2=6/n. Cross multiply

    3n=12. Divide both sides by 3

    3/3n=12/3

    n=4

    Therefore n equals 4

    Slope (m) = 2nd y value minus 1st y value divided by 2nd x value minus the first x value

    m=y2-y1/x2-x1

    m=5 - (-1) / - 2-9

    m=5+1/-2-9

    m=6/-11

    Thus the slope is - 6/11
