Answer

wik8947201 -3y= -2x+1/:(-3)
y=2/3x-1/3
Proste rownolegle maja wspolczynniki kierunkowe rowne
y=2/3x+b Podstawiamy wspolrzedne P
2/3*(-2)+b=4
-4/3+b=4
b=4+1 i 1/3
b=5 i 1/3
y=2/3x+16/3
Proste prostopadle maja wspolczynniki kierunkowe, takie ze a1*a2=-1
2/3a=-1 /:2/3
a=-3/2
y=-1,5x+b
-1,5*(-2)+b=4
3+b=4
b=4-3=1
y=-1,5x+1

Zgłoś nadużycie! 2x-3y-1=0 P(-2,4)
-3y=-2x+1 /:(-3)
y=2/3x-1/3

Prosta równoległa:
l: y=2/3x+b
4=2/3*(-2)+b
4=-4/3+b
b=4+4/3
b=5i1/3
l: y=2/3x+5i1/3

Prosta prostopadła:
k: y=-3/2x+b
4=-3/2*(-2)+b
4=6/2+b
4=3+b
b=4-3
b=1
k: y=-3/2x+1
