PracticeWrite the equation of the line that passes through the given point and is perpendicular to the given line. Write the answer in slope-intercept form.

P(-3, 3), http://www.webassign.net/images/cleardot.gify+ 9x= -15

i did the whole y-y1=mx(x-x1)

and i came up with y-3=-1/9x[x-(-3)]

= y-3=-1/9(x+3)

=9y-27=-x-3

=9y=-1/9x+8/3

What am I doing wrong? PLEASE HELP
