Answer:

Step-by-step explanation:
Calculate AC and AB using the distance formula
d = 
with (x₁, y₁ ) = A(1,8) and (x₂, y₂ ) = C(4,2)
AC = 
= 
= 
=
=
= 3
Repeat with
(x₁, y₁ ) = A(1, 8) and (x₂, y₂ ) = B(2, 6)
AB = 
= 
= 
= 
So AB =
and AC = 3
Thus
AC = 3AB

Answer:
y = 1/3x - 3
Step-by-step explanation:
If the line is perpendicular to y = -3x + 11, it means that the two gradients multiply to make -1.
So the gradient of the perpendicular line is 1/3 (-3 × 1/3 = -1)
y = 1/3x + c
Next, substitute x = -9, and y = -6 to find the y intercept, or c:
-6 = 1/3(-9) + c
-6 = -3 + c
c = -6 + 3
c = -3
The equation of the line is y = 1/3x - 3
