If the correlation between two variables x and y in given by 2x 3y 4=0...
Identifying Positive/Negative/Zero Correlation from Equation:

  • When the coefficient of x and y have the same sign, the correlation is positive.

  • When the coefficient of x and y have opposite signs, the correlation is negative.

  • When either the coefficient of x or y is zero, the correlation is zero.



Solution:
The given equation is 2x + 3y + 4 = 0.

  • The coefficient of x is 2 which is positive.

  • The coefficient of y is 3 which is also positive.


Therefore, the correlation between x and y is positive.

Answer: Option A.0 (since positive correlation is not an option)
