<h2>Answer:   
y = - ¹/₂ x + 5
</h2>
<h3>Step-by-step explanation:

<u>Find the slope of the perpendicular line</u>
When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.
                  ⇒  if the slope of this line = 2     (y = 2x + 2)
                       then the slope of the perpendicular line (m) = - ¹/₂
<u>Determine the equation</u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  
                                ⇒  y - 3 =  - ¹/₂  (x - 4)
We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:
                              since   y - 3 =  - ¹/₂  (x - 4)
                                               y = - ¹/₂ x + 5   (in slope-intercept form)
