Question

Determine o coeficiente angular (m) de cada uma das equacoes x+2y-3=0
2x-y-4=0 3×+5y-5=0 4×+2y-8=0

Answer 1

x+2y-3=0
2y= -x-3
y= - 1/2 x-3/2

m= -1/2


2x-y-4=0
-y=4-2x
y= 2x+4

m= 2


3x+5y-5=0
5y= -3x+5
y= -3/5 x+5/5
y= -3/5x+1

m= -3/5



4x+2y-8=0
2y= -4x +8
y= -4/2 x+8/2
y= - 2x +4

m= -2
