Question

determine a equação geral de linha reta a- A(5-3) e m=6 b- A(2.5) e m=2 c- A(4.3) e m=-3 D- A(2 -3) e m=4​

Answer 1

Resposta:

A) A(2,5)

m=2

y-yo=m(x-xo)

y-5=2(x-2)

y-5=2x-4

y-2x-5+4=0

-2x+y-1=0

B) A(5,-3)

m=6

y+3=6(x-5)

y+3=6x-30

y-6x+3+30=0

-6x+y+33=0

C) A(4,3)

m=-3

y-3=-3(x-4)

y-3=-3x+12

y+3x-3-12=0

y+3x-15=0

D) A(2,-3)

m=4

y+3=4(x-2)

y+3=4x-8

y-4x+3+8=0

y-4x+11=0
