Equation
--------------------------------------------------------------------------
$y - 9 = - \dfrac{1}{2} (x + 2)$

--------------------------------------------------------------------------
Rearrange the equation
--------------------------------------------------------------------------
$y - 9 = - \dfrac{1}{2} (x + 2) \\ \\
 y - 9 = - \dfrac{1}{2}x - 1 \\ \\
 y - 9 + 9 = - \dfrac{1}{2}x - 1 + 9 \ \Longleftarrow \text{add 9 to both side} \\ \\
 y = -\dfrac{1}{2}x + 8$

--------------------------------------------------------------------------
slope of the perpendicular line
--------------------------------------------------------------------------
slope = 2

(*the slope of the perpendicular line is the negative reciprocal of the slope of line)

---------------------------------------------------------------------------
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

----------------------------------------------------------------------------
Answer: y = 2x + 4
