Question

The graph of a proportional relationship is always a straight line passing through the __________.

• A. origin
• B. $X$-axis
• C. $Y$-axis
• D. both (A) and (B)

Answer 1

The correct option is A origin

The graph of a proportional relationship is always a straight line passing through the origin.
Note: If a graph is a straight line but does NOT pass through the origin, or if it passes through the origin but is not a straight line, then it does not represent a proportional relationship.
For a proportional relationship, both the conditions, i.e., being a straight line and passing through the origin are mandatory.
