It helps to visualize the awning as a line whose rise is the height of the window and whose run is how far it extends from the window's base. See the picture attached.
The slope of a line is equal to rise over run. In this case, that would be 4 over 2. You can simplify that to a slope of 2.

To make the perpendicular line, it is convenient to swap the x- and y-coefficients and negate one, then offset the x- and y- by the point value:
.. 2(x +2) +3(y -1) = 0
This equation can now be put into any desired form. Based on the given equation, it looks like you would like "standard form."
.. 2x +3y = -1
.. 2(x +2) +3(y -1) = 0
