[25 Points] Consider the following nonlinear system of equations: Use two iterations of Newton’s method to approximate a solution of this system with the initial guess (x0 , y0)T = (1, 1).  

BONUS:  Suppose you have a linear correlation coefficient of either 1 or -1 (which indicates perfect linear correlation, or that the response variable is wholly determined by a linear polynomial based on the predictor variable). What would be the corresponding value of the test statistic given a test to determine whether r shows positive or negative correlation? Explain your answer in writing below, using relevant formula and mathematical analysis.
