Wśród prostych : k,l,m,n,o,p wskaż pary prostopadłych
k : y = 2/5 x + 2 , l : y = 5/2x - 4
m : y = 1 1/2x + 4 , n : y = -2,5x - 4
o : y = -0,4x + 2 , p:y = -2/3x - 2

Proste są prostopadłe wtedy gdy a1*a2=-1
===================================
Proste k i n:
2/5*(-2,5)=2/5*(-5/2)=-1
=====================
Proste m i p:
1 1/2*(-2/3)=3/2*(-2/3)=-1
====================
Proste l i o:
5/2*(-0,4)=5/2*(-2/5)=-1
=====================
