For 1-10, determine whether the lines are parallel, perpendicular or neither.
One line passes through the points (-1, 4) and (2, 6); another line passes through the points (2, -3) and (8, 1).
One line passes through the points (4, -3) and (-8, 0); another line passes through the points (-1, -1) and (-2, 6).
One line passes through the points (-3, 14) and (1, -2); another line passes through the points (0, -3) and (-2, 5).
One line passes through the points (3, 3) and (-6, -3); another line passes through the points (2, -8) and (-6, 4).
Both lines pass through the point (2, 8); one line also passes through (3, 5), and the other line has slope 3.
