Find an equation perpendicular to the given function if it passes through (-3,9)
First, we need to determine the slope of:
The slope intercept of an equation is in form;
<em>Where m represent the slope</em>
Comparing to
;
We'll have that
Going from there; we need to calculate the slope of the parallel line
The condition for parallel line is;
Substitute
Divide both sides by -2
The point slope form of a line is;
Where and
becomes
Open the inner bracket
<em>Hence, the point slope form of the perpendicular line is: </em>

Just subsitute values for x and get values for y

(0,-2)
(1,1)
(-1,-5)
(-2,-8)
