No. If we had y = 5x, then it would. But y does not vary directly as x because in order to do so, we'd need y = kx for some constant k. That's what it means for two variables to "vary directly" or be in "direct proportion".

The relation is linear and so the two vary directly. Despite the extra constant term, the two derivatives are related by a constant
Dy/Dx = 5
and so they vary directly.

por supuesto, nena!!! es una ecuacion lineal de 1º grado en x con una pendiente dy/dx = 5 y por lo tanto varia en forma proporcional. !!!!

y is the dependent variable
it varies as x varies but is not proportionate
