    First find the slope of the line given by changing it into slope intercept form.

    0.5x-5y=9

    -5y=-0.5x+9

    y=0.1x-9/5

    The slope is 0.1

    To find a perpendicular slope, find the negative reciprocal.

    The reciprocal of 0.1 is 10

    The negative of 10 is - 10

    Final answer: - 10
