check the slopes; parallel lines have same slope
A.
and in slope-intercept form
and ...same slope; so, these two lines are parallel to each other

we will check these too,
B.
and
and ... slopes are not same;...these two lines are NOT parallel to each other

C.
and
and ...same slope; so, these two lines are parallel to each other

D.
and
and }}}... slopes are not same;...these two lines are NOT parallel to each other
