Answer:

The correct option is B.

Step-by-step explanation:

The slope of a line is calculated as

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The slope of line is undefined if there is no change in the values of x. It is possible only in the case of vertical line.

Graph B represents a vertical line. So the slope of the line in graph B is

[tex]m_B=\infty[/tex]

The slope of line B is undefined, therefore the correct option is B.
