write an equation of the line containing the given point and perpendicular to the given line (6,7);6x+=9

I am having a terrible time figuring out the last part. I would appreciate any help. Thank you.

    Your equation is not complete.
    6x + = 9?

    Sorry, I'm stressing badly. The equation is (6,7);6x+y=9. Thank you kindly.

    (6,7);6x+y=9.

    y = mx + b
    6x + y = 9
    y = -6x + 9
    m = -6

    m1*m2 = -1
    -6*m2 = -1
    m2 = 1/6

    So, the slope of the perpendicular line is 1/6.
    y = 1/6 x + b

    Now find b with point (6,7).
    y = 1/6 x + b
    7 = 1/6 (6) + b
    7 = 6/6 + b
    7 = 1 + b
    b = 6

    y = 1/6 x + b
    y = 1/6 x + 6
