If you mean: y=2x+4 and x+2y=12 => y=-1/2x+6 which means that they are perpendicular to each other.
Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given line is parallel to some lines and perpendicular to others.
They are both parallel because the slope or gradient is the same but the y intercept is different.
The slope of both lines is 8. So they're parallel.
If the second equation is: y minus 2x equals 3, then:y - 2x = 3 ⇒ y = 2x + 3 and it is parallel to y = 2x.Otherwise (with with missing operator as "plus", "multiply" or "divide"), the lines are neither parallel nor perpendicular.
No. They are parallel.
[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.
One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.
One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.
The second equation works out as y = -1/2x+6 therefore it is perpendicular
They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.
The two lines are: 2x+4y=2 4x+2y=5 Le't write them in slope intercept form 4y=-2x+2 or y=-1/2+1/2 AND 2y=-4x+5 or y=-2x+5/2 Now we use the fact the parallel lines have the same slope. One line here has slop =1/2 and the other has -2. Next if lines are perpendicular the product of the slopes is -1. This is not the case here either. So the answer is NEITHER!
Parallel lines never touch each other, they run side by side, like railroad tracks, or this equal sign = Perpendicular lines cross each other at 90 degrees, so it looks like a t or a plus sign, +
