You can put this solution on YOUR website! Write an equation of the line that passes through the given point and is perpendicular to the given line.
(1,-1), y=3x+2
------------
Since the given slope is 3, the slope you want is -1/3.
Equation form is y = mx +b
Substitute to solve for "b":
-1 = (-1/3)*1 + b
b = -1 + (1/3) = -2/3
------------------------
Equation:
y = (-1/3)x + (-2/3)
