If the regression equation of x on y is given by mx – y + 10 = 0 and the equation of y on x is given by -2x + 5y = 14, determine the value of ‘m’ if the coefficient of correlation between x and y is 1/√10

Step-by-step explanation:
If the regression equation of x on y is given by mx – y + 10 = 0 and the equation of y on x is given by -2x + 5y = 14, determine the value of ‘m’ if the coefficient of correlation between x and y is 1/√10
Two regressions line :
➮ mx – y + 10 = 0
➮ mx = y - 10
➮ -2x + 5y = 14
➮ 5y = 2x + 14
Put the values,
Squaring both the sides,
