If both the values of x and y is together positive and also at the same time negative then it probably would indicate that the values consisting x and y are in direct proportionality or in a positive correlation with one another. The values simultaneously increases and decreases at the same time. Consider x = y or –x = -y.
These equations mean that above explained phenomenon between these two occurring unknowns.
The value of x − y being negative implies that x < y , meaning x is less than y. Both variables are positive, confirming that x is a smaller positive value compared to y. Therefore, x is positive but less than y, which also remains positive.
