Bonjour j'ai un exo de math a faire que je ne comprend pas:
g est une fonction affine de la forme g(x)=ax+b telle que g(-1)=3 et g(3)=1
1)calculer a et b
2)en deduire une expression algebrique de la fonction g
merci d'avance

1) a: coefficient directeur
soit A (-1,3) et B (3,1)
a = (yb-ya)/(xb-xa) = (1-3)/(3-(-1))= -2/4 = -1/2
donc y=-0,5x+b
soit ya=-0,5xa+b ou yb=-0,5xb+b
ce qui équivaut à 3=-0,5*(-1)+b
3=0,5+b
2,5=b
donc y = -0,5x + 2,5
2) g(x)= -0,5x + 2,5
