If the point p( -3/5,v) lies on the unit circle and p is in the third quadrant, what does y equal?

  y = -4/5

Step-by-step explanation:

Both coordinates are negative in the 3rd quadrant. The value of y is the other leg of the right triangle with hypotenuse 1. The Pythagorean theorem is helpful.

  y = -√(1 -(-3/5)^2) = -√(1 -9/25) = -√(16/25)

  y = -4/5
