    -1

    Step-by-step explanation:

    Given equation of line is:

    x - y = 8

    In order to find the slope of other line we have to convert the given equation in standard form

    So,

    -y = - x + 8

    Multiplying the equation with - 1

    y = x - 8

    The co-efficient of x is the slope of the line.

    Here the co-efficient is 1 so the slop of line is 1.

    We know that the producct of slopes of perpendicular lines is - 1.

    Let m2 be the slope of the other line then

    1 * m2 = - 1

    m2 = - 1

    So the slope of line perpendicular to line x-y = 8 will be: - 1 ...
