I was searching for this type of question on the main
but could not find it
also no help using Approach0.xyx
The question is -
"The variables $X$ and $Y$ are connected by the equation $aX+bY+c = 0$, show that the correlation between them is -1 if the signs of $a$ and $b$ are the same and $+1$ if they are different."
