BONSOIR tout le monde pouvez vous me dire si mon calcul est bon merci y=ax +b s= 1 ; 6
6= a (1) +3
6= 1a +3
-3-6 = 1a
-9 = 1a 1a = -9
a = -9/1
a = -9
y = ax + b s = 1 ; 6 B= 7
6 = a (1) + 7
6 = 1a + 7 -7 + 6 = 1a
-1 = 1a
1a = -1
a = -1/1
a = -1
6= a (1) +3
6= 1a +3
-3-6 = 1a
-9 = 1a 1a = -9
a = -9/1
a = -9
y = ax + b s = 1 ; 6 B= 7
6 = a (1) + 7
6 = 1a + 7 -7 + 6 = 1a
-1 = 1a
1a = -1
a = -1/1
a = -1
