    covarience MATH EMERGENCY

    I have one hour to solve this problem if anyone could help. it would mean a lot.

    the random variables X and Y are correlated via the equation y = 1 + 5X.
    The same standard deviation of X, Sx = sqrt(5). find the sample covariance Sxy.

    Any help would be greatly appreciated.
    Time is of the essance.
