Answer:

No.

It doesn’t pass through the origin point.

Explanation:

Remember that for a graph to represent a proportional relationship, it must meet the following three criteria:

  • It must pass through the origin point.
  • It must be a line.
  • And it cannot be vertical or horizontal.

Our graph is indeed a line.

It is also not vertical or horizontal.

However, it does not pass through the origin point (0, 0).

Therefore, this graph is not a proportional relationship.
