See explanation.

#### Explanation:

First we have to transform the given equation to form

Now we can write the equation of a line perpendicular to the given one.

Two lines are perpendicular if and only if product of their slopes is

So the line we are looking for has equation:

Now we have to calculate the value of

To do this we have to put the point's coordinates as

Finally the line perpendicular to
