The explanation is too good to understand. neatly explained. when i worked out the same problem, i have got cov(x,y) is 8.25 but you said -11. I have used 1/N ( summation of (x,y)) mean(x) * mean(y). In this clip, you have used N-1, If i use N, it gives -8.25. can you explain which is correct formula? when to use N and when to use N-1?. Thanks

The covariance of the two variables x and y is equal to the summation of the products of the differences of each value and the mean of its variables and finally divided by one less than the total number of data points. So, cov(x,y)=-11........ Hope your doubt is cleared!! :)
