Question

decide whether the pair of lines is parallel, perpendicular, or neither
2x+4y=6
2x+4y=1

Answer 1

write them both as y=mx+b

Answer 2

if the slopes or opposite reciprocals of each other then they are perpendicular
if the slopes are the same then they are parallel
if neither of the above, then say neither

Answer 3

They are parallel as the slopes are identical

Answer 4

4y = -2x +6
4y = _ 2x +1
y = -1/2 x +6
y = -1/2 +1
m = -1/2
the lines are parallel
