Rewrite the slope 0.2 into fraction form

If you're given a slope of , you can find the perpendicular slope by negating and inverting the given slope.

In other words, use this formula to find the perpendicular slope:
where m is the given slope and is the perpendicular slope

plug in

Flip the second fraction and multiply

Multiply

Reduce

So the perpendicular slope is
