Question 196166
(1)  y = -3x -2
(2) 6x +2y =-4
substitute  (1)  into (2)
6x +2(-3x-2) = -4
6x -6x -4 = -4
-4 = -4
,
This  is  an  indication  that  the  solution  is  all  real  numbers
and  that  the  lines  are  coincident
.
looking  at  (1),, if  we  multiply  by  2  throughout  and  rearrange  it  is  the  same  as  (2)
.
y = -3x -2
2y =-6x -4
or  6x +2y = -4,  and  (1) =(2)  exactly
.
the  lines are  on  top  of  each  other
Some  of  the  answers  that  fit  include,  (0 -2), (1, -5), (2, -8)
