Question

Out of the two lines of regression given by
x + 3y - 7 = 0 and 2x + 5y - 10 = 0, which one is the
regression line of y on x ?​

Answer 1

Answer:

x=-5,y=4

Step-by-step explanation:

x + 3y=7 - - -. eq 1

2x + 5y = 10 ----- eq 2

multiply eq 1 by 2

so, 2x +6y = 14 ------ eq3

subtract eq 2 from 3

so y = 4 and x= -5
