Answer:
Step-by-step explanation:
L : y = -4x + 3
with a slope of -4.
Any line perpendicular to L will have a slope m such that
m ( -4) = -1, or m = 1/4
Any line perpendicular to L passing through point (a,b) will therefore have the form
P : (y-b) = (x-a)/4
When (a,b) = (8,1) as given, then substitute in P to get
P : (y-1) = (x-8)/4
y=x/4 -2 + 1
y = x/4 -1
