Since x=8/3 is a vertical line,the slope is undefined,
2/33 * 1/5 * 11/10 = (2 * 1 * 11) / (33 * 5 * 10) = 22/1650 reduces to 1/75
That is 6 I believe
3 squared equals 9
9*2=18
18/3=6
The unit Circle is a platform for describling all the possible angle measures from 360 degrees all negative of those angles plus all the multiplies of the positive and negative angles from negative infinity to postive infinity hope this helps you
