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
------------------
Equation:
y = (-1/5)x - (8/5)
========================
Cheers,
Stan H.
