Question 177227
{{{drawing( 300, 300, -6, 5, -8, 3,grid( 1 ),
circle(-5,1,.2),
circle(-3,1,.2),
blue(line(-5,1,-3,1)),

circle( -3, -7, .2 ),
circle( 4, -7, .2 ),

green(line( -3, -7, 4, -7)))}}}
From the graph, it looks like the lines are parallel.
Parallel lines have identical slopes. 
We can verify that the slopes are identical.
{{{m=(DELTA*y)/(DELTA*x)}}}
.
.
.
{{{m[1]=(1-1)/(-5-(-3))=0}}}
.
.
.
{{{m[2]=(-7-(-7))/(-3-4)=0}}}
The slopes are identical, the lines are parallel.
