Question

10.What is the rate of change of a line containing the points (9,5) and (9,16)?A.undefinedB.0C.11/18D.7/6

Answer 1

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,

$m=\frac{y_2-y_1}{x_2-x_1}$

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

$\begin{gathered} m=\frac{16-5}{9-9} \\ =\frac{11}{0} \\ =\text{undefined} \end{gathered}$

So answer is undefined.

Option A is correct.
