Answer:
To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use

Then we just plug in the point we want to cross and solve for the constant.
Step-by-step explanation:
we see that m = 
so, 
now we have the equation

plugging in (6, -4) we get

This gives us our function
