Given:

The line containing the points (9,5) and (9,16).

Explanation:

The rate of chage of line passes through point (x_1,y_1) and (x_2,y_2) is,

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

Determine the rate of change of line passes through line (9,5) and (9,16).

[tex]\begin{gathered} m=\frac{16-5}{9-9} \\ =\frac{11}{0} \\ =\text{undefined} \end{gathered}[/tex]

So answer is undefined.

Option A is correct.
