Bonsoir,
1) a) +2
b) -3
2) a) +1/2
b) +5/4
3) a) (5-2)/(0-(-4)) = 3/4
b) (-2-2)/(2-(-4)) = (-4)/(-6) = 2/3
c) (-2-5)/(2-0) = -7/2
Réponse :
Bonsoir ,
Explications étape par étape
1) le coefficient de la droite AB
a) coef : 2
b) coef. : -3
2) a) coef. : 0,5
b) coef. : 0,88
3) a) AB = (5-2) / (0-( -4)) =3/4
b) AC = ( yc-ya)/(xc-xa) = (-2-2)/ (2- -4) = -4/(2+4) = -4/6= - 2/3
c) BC = yc-yb/xc-xb = -2-5/2-0 = -7/2
