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

Question

anonymous · Answer

yes same slopes

anonymous · Answer

determine the slope.  Parallel lines have the same slope.
y=-1/2x+3/2
y=-1/2x+1/4
so you are correct

anonymous · Answer

2x+4y=6--->y=-1/2x+3/2
2x+4y=1--->y=-1/2x+1/4
they have same gradient that is m so these lines are parallel

anonymous · Answer

In general, the line ax + by + c = 0 has slope of - a/b.

Then the slope of your first line is - 2/4 or -1/2 and so is the second therefore the lines are parallel.

A line perpendicular to another with slope m would have a slope of - 1/m (ie the product of the slopes is -1).
