A student claims that they can use rules about the coordinates of point A to tell wether the cosine of the angle formed by the x-axis and the kind that connects the origin to point A will equal a positive or a negative value. Which of the following statements supports the student’s claim? A) if the y-coordinate is positive, the cosine will equal a positive charge.

B) if the x-coordinate are negative, the cosine will equal a negative value.

C) if the x-coordinate is in Quadrant l, the cosine will equal a negative value.

D) if the x- and y-coordinates are negative, the cosine will equal a positive value.
