Answer:
Lines A and B are neither parallel nor perpendicular lines.
Explanation:
For two lines,
if their slopes are equal then the lines are parallel; and
if the slope of one line is the negative reciprocal of the slope of the other line, then the two lines are equal.
Finding the slopes of line A and B:
and neither they are the negative reciprocal of each other so the lines A and B are neither parallel nor perpendicular lines.
The equation of the line passing through the points and is
Then
1) the equation of line A is
2) the equation of line B is
Since then lines are not perpendicular.
Since then lines are not parallel.
Answer: neither parallel, nor perpendicular
