The best interpretation of what you want is the line perpendicular to and contains the point (1,-1).

The slope of the line you want is +. We initially do not know the y-intercept, b but can solve for b and then substitute the given point of (1,-1).




Now let x=1 and y=-1



Your equation is then found,
