False.
The equation \( y = 7x - 2 \) does not represent a proportional relationship because it does not pass through the origin (0,0). A proportional relationship can be expressed in the form \( y = kx \), where \( k \) is a constant. In this case, the presence of the \(-2\) indicates that there is a constant that shifts the line vertically, thus losing the property of proportionality.
