A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true?
a: a, b, c, and d lie on the same line.
b: ab and cd are perpendicular lines.
c: ab and cd are parallel lines.
d: ab and cd are intersecting lines but are not perpendicular.
e: ac and bd are parallel lines.

The true statement about the coordinate points is that : line AB and line CD are intersecting lines but are not perpendicular.

• Lines AB and CD meet a point, thus means that they are not parallel as parallel lines never meet.

• The point of intersection of lines AB and CD isn't at a right angle. Hence, lines AB and CD are not perpendicular

• AC and BD are not parallel lines, because both lines do not have the same separating distance.

Therefore, lines AB and CD are intersect, however, they do not intersect at right angles. Hence, both lines are intersecting lines but not perpendicular.
