When a line is given in the form
The slope of the line is m. So, in this case, the slope of is -1.
Given a slope , you find the slope of a perpendicular line
by imposing
So, if the given line has slope -1, a perpendicular line has slope given by
and thus
So, we want a line with slope 1 and passing through (9,2). Using the fomula
we get
