Equation of the new perpendicular line is 
How to calculate the new perpendicular line?
The given equation is:
y- 8=4 (x-5)
This equation is of the point- slope form

y - 8 = 4( x-5 )
So, the slope (m) is m = 4
The points 
Hence, slope of the line perpendicular to the given line is
m = 
The equation of the new perpendicular line is :

Since the points through which the line passes is not given.
