Question

as retas 3x+2y-1=0 e -4x + 6y - 10=0 são

paralelas
coincidentes
perpendiculares
concorrentes e nao perpendiculares
nd

Answer 1

COEFICIENTE ANGULAR DA RETA = -a/b
m = -a/b
Se as retas forem paralelas, mr = ms
mr = -3/2
ms = -(-4)/6 = 4/6 = 4:2/6:2 = 2/3
Se as retas forem perpenediculares, mr . ms = -1
-3/2 . 2/3 = -6/6 = -1
As retas são perpendiculares
