Question

1=determine o coeficiente angular da reta que passa pelos pontos:

A=a (3,2) b (23,21)
B=a (2,23) b (24,3)
C=p (3,2) q (3,22)
D=m (21,4) n (3,2)
E=p (5,2) q (22,23)

Answer 1

m = yA - YB\xA - xB

a) 2- (21)/ 3 -(23)= -19/-20 = 19/20

b) 23-(3)/ 2-(24)= 20/-22= -10/11

c) 2-(22)/3-(3)= 20/0= i

d) 4-(2)/21-(3)= 2/19

e) 2-(23)/5-(22)= -21/-17= 21/17
