Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
The slope is undefined because you need a y intercept as well.
Plug the given x and y values (x, y) into the equations and solve
It look like the second equation is the answer.
Answer:
Christy is correct
Step-by-step explanation:
you dont say the numbers in words all the time, so it makes a lot more sense.
