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.
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.
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.
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.
[ 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.

If you mean: y=2x+4 and x+2y=12 => y=-1/2x+6 which means that they are perpendicular to each other.
No. they are parallel, since the slopes are both equal in this case 3. To be perpendicular the product of the slopes of both lines is equal to -1 (i.e., m1*m2 = -1).
No.
