Let X and Y be two related variables. The two regression lines are given by `x-y+1=0` and `2x-y+4=0`. The two regression lines pass through the point:

Options

A. `(-4,-3)`
B. `(-6,-5)`
C. `(3,-2)`
D. `(-3,-2)`

Answer

D

Explanation

Given regression lines are `x-y+1=0` and `2x-y+4=0` only point `(-3,-2)` given in option (d) satisfies the both equations.
Hence, The two regression lines pass through the point `(-3,-2)`.
