What is the equation of a line that is perpendicular to y=4x+5 and passes through the point (8,3)?

A. y= -1/4x+5

B. y= -1/4x+3

C. y=1/4x+1

D.y=-1/4x-8

Answer 1

y-3=-1/4(x-8)
y-3=-1/4x+2
+3 +3
——————
y=-1/4x+5

Answer 2

Answer: A is the right answer

Explanation:

y=4x+5

m=-4/-1=4

y-3=-1/4(x-8)

4(y-3)=-x+8

4y-12=-x+8

4y=-x+20

y=-1/4x+5
