X:
A. \left ( \frac{4}{5},\ y \right )
B. \left ( \frac{1}{3},\ y \right )
C. \left ( \frac{\sqrt{2}}{3},\ y \right )
D. \left ( \frac{2}{3},\ y \right )

Y:
A. y = \pm \frac{\sqrt{5}}{3}
B. y = \pm \frac{\sqrt{7}}{3}
C. y = \pm \frac{3}{5}
D. y = \pm \frac{2\sqrt{2}}{3}

Answer 1

Matching the x-coordinates with their corresponding pairs of y-coordinates on the unit circle:

X:
A. (4/5, y) - C. (2/3, y)
B. (1/3, y) - D. (sqrt(2)/3, y)

Y:
A. y = +- sqrt(5)/3 - C. y = +- 3/5
B. y = +- sqrt(7)/3 - D. y = +- 2sqrt(2)/3
