Question

1 ) calcule os coeficientes angulares abaixo : A ) (1 ,3 ) B (5,9 ) B ) A (- 1, -3 ) B ( 5,9 ) C ) A ( 2 ,8 ) B ( 5,7 ) D ) A ( 1 ,0 ) B ( 3,6 )

Answer 1

m=$\frac{yb-ya}{xb-xa}$
m representa coeficiente angular

a)m=9-3/5-1
m=6/4
simplificando: 3/2.

b)m=9-1/5+1
m=8/6
simplificando: 4/3

c)m=7-8/5-2
m=-1/3

d)m=6-0/3-1
m=6/2
m=3
