Answer:

It does not represent a proportional relationship; it represents a non-proportional relationships.

Step-by-step explanation:

1. All proportional relationships follow the following equation: y = kx.

  • y = y-coordinate
  • k = constant of proportionality/slope
  • x = x-coordinate

2. Because the equation y = 2x + 4 does not follow y = kx (because it has + 4), it is not proportional.

Therefore, the equation does not represent a proportional relationship.
