Answer:

Step-by-step explanation:
Given
The given equation is a differential equation


By separating variable
⇒

Now by taking integration both side

⇒
Where C is the constant




from above equation we can say that
When t will increases in positive direction then
will decreases it means that
will increases, so y will decreases. Similarly in the case of negative t.
