Using implicit differentiation, it is found that y is changing at a rate of 10 units per second.
---------------------
The equation is:

Applying implicit differentiation in function of t, we have that:

- x-values changing at a rate of 2 units per second means that

- Point Q(1,4) means that
.
We want to find
, thus:


y is changing at a rate of 10 units per second.
