Experimentally the following data are obtained:

x	y
280	253
276	232
220	200
132	136

Using the method of least squares adjust the function. Indicate the equations in matrix form and the values of the determinants of each matrix. Calculate with those values A and B and the correlation coefficient r.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
