The bivariate data set contains only two points (−1,1)(-1,1) and (3,2) What will be the line of regression of y on xx ?

Options

  1. Ax−4y+5=0x-4 y+5=0
  2. B3x+2y−1=03 x+2 y-1=0
  3. Cx+4y+1=0x+4 y+1=0
  4. D5x−4y+1=05 x-4 y+1=0

Correct answer

A. x−4y+5=0x-4 y+5=0

Step-by-step solution

For line of regression of yy on xx, the line will be one which satisfy both points. Clearly, x−4y+5=0x-4 y+5=0 satisfy (−1,1)(-1,1) and (3,2)(3,2) both. Hence line is x−4y+5=0x-4 y+5=0.
