--------------------------------------------------------------------------
slope of the perpendicular line
--------------------------------------------------------------------------
slope = 2
(*the slope of the perpendicular line is the <span>negative reciprocal of the slope of line)</span>
---------------------------------------------------------------------------
Substitute slope into equation y = mx + c
---------------------------------------------------------------------------
y = 2x + c
---------------------------------------------------------------------------
Find y-intercept
---------------------------------------------------------------------------
y = 2x + c
At point (0, 4)
4 = 2(0) + c
c = 4
----------------------------------------------------------------------------
Substitute y-intercept into the equation y = 2x + c
-----------------------------------------------------------------------------
y = 2x + 4
----------------------------------------------------------------------------
