Question 738547
The slope of this given line is 1/2


Flip the fraction to get 2/1 = 2


Flip the sign to get -2, this is the perpendicular slope. A good way to remember finding it is: Start with the given slope, turn it into a fraction (if necessary), then flip the fraction and flip the sign to get the perpendicular slope.


So the answer is <font color="red">-2</font>
