The problem asks whether the equation $y = 7x^2$ is proportional or not.

1. Problem Description

The problem asks whether the equation $y = 7x^2$ is proportional or not.

2. Solution Steps

A proportional relationship can be written in the form $y = kx$, where $k$ is the constant of proportionality. The graph of a proportional relationship is a straight line that passes through the origin.

The given equation is $y = 7x^2$. This equation contains $x^2$, which means that $y$ is not directly proportional to $x$, but rather to $x^2$. The graph is a parabola, not a line.

Therefore, the relationship is not proportional.

3. Final Answer

Non-Proportional
