Rewrite the slope 0.2 into fraction form
0.2=2%2F10

If you're given a slope of m=2%2F10, you can find the perpendicular slope by negating and inverting the given slope.

In other words, use this formula to find the perpendicular slope:
m%5Bp%5D=-1%2Fm where m is the given slope and m%5Bp%5D is the perpendicular slope

m%5Bp%5D=-1%2F%282%2F10%29 plug in m=2%2F10

m%5Bp%5D=%28-1%2F1%29%2810%2F2%29 Flip the second fraction and multiply

m%5Bp%5D=-10%2F2 Multiply

m%5Bp%5D=-5 Reduce


So the perpendicular slope is -5
