Concepts

A graph shows a straight line that crosses the y-axis at
$(0, 3)$ instead of at the origin. Is this relationship
proportional?

No — a proportional relationship's graph must be a straight line AND pass through the origin; this line misses the origin.

Yes — any straight-line graph represents a proportional relationship.

Yes, as long as the line has a positive slope.

No — proportional relationships can never be represented by a straight line.
