Question

Write an equation for the line perpendicular to y = 5x – 12 that contains (–3, –1).

Answer 1

The answer is B

Write an equation for the line perpendicular to y = 5x – 12 
that contains (–3, –1).
----------------
The given equation has slope = 5
----
The desired equation must have slope = -1/5
-------
Form: y = mx + b
Solve for "b" when m = -1/5 and y = -1 when x = -3

==================
-1 = (-1/5)(-3) + b
-1 = (3/5) + b
b = -8/5
------------------
Answer=y + 1 = 5(x + 3)

Answer 2

Y = 5x - 12
Here, slope = 5
Perpendicular line slope = -1/5  [ opposite and reciprocal ]

Now, y - y1 = m(x - x1)
y + 1 = -1/5 (x + 3)

In short, Your Answer would be Option B

Hope this helps!
