Segment AB has coordinates A(5, 6) and B(-2, 2). Segment CD has coordinates C(-4, -9) and D(-8, -2). Determine if AB and CD are parallel, perpendicular, or neither. Justify your answer. A. The segments are parallel because the slopes are the same.
B. The segments are perpendicular because the slopes are opposite reciprocals of each other.
C. The segments are not parallel or perpendicular because they are both negative.
D. The segments are parallel because the slopes are opposite reciprocals of each other.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
