In the provided image, the question asks which graph represents a linear function. Let's analyze each option:

• Graph A: The curve bends and changes direction, which indicates that it is not a straight line. Therefore, this is not a linear function.

• Graph B: This graph shows a straight line that moves diagonally, which is characteristic of a linear function. Therefore, this represents a linear function.

• Graph C: This is an ellipse, and an ellipse is not a linear function as it is a closed curve, not a straight line.

• Graph D: The curve is non-linear, as it bends. This is also not a linear function.

Thus, Graph B represents a linear function.
