In python, define a linear regression function, without using import command.

def regressionSlopeIntR(L, M): Find the usual line of best fit using linear re- gression. Report its slope and intercept, together with the coefficient of correlatioin to call in order to calculate the values. Here, L holds the x values, and M holds the Please be very careful to note that c (r). The symbols ??, ??2 and ?2y are to there to tell you which function you need y values. Note that Sy and Sy2 make use of the same functions as ?? and ??2. so note, n 1s the length of each list. 1S slope - intercept
