If the slope of the equations are the same then they are parallel
If the slope of the equations are minus reciprocal then they are perpendicular
If the slope of the equations are different then they are neither
I'll get back to you as soon as I've seen the video.
Neither perpendicular nor parallel
perpendicular.
PERPENDICULAR
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
Neither perpendicular nor parallel

Two lines are parallel if and only if they have the same slope. Two lines are perpendicular if the product of their slopes is -1. If neither of these conditions are met, the lines are nether parallel, or perpendicular.
No, oblique lines are neither parallel nor perpendicular
That depends on the specific situation. You may want to measure angles (perpendicular lines are at a right angle, i.e., 90°). If you have equations for line, write them in the slope-intercept form. Parallel lines have the same slope. If lines are perpendicular, the product of their slopes is -1.
Parallel
Diagonal
Lines that are neither parallel nor perpendicular.
Magnetic field lines are usually depicted as curved lines extending away from the source. They are neither parallel or perpendicular (though they appear more parallel than perpendicular).
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
neither
In two dimensions: They are parallel if their gradients are the same. They are perpendicular if the product of their gradients is -1. Otherwise they are neither. The nature of the question suggests that you have not yet studied lines in 3 or more dimensions.
