Answer:
[tex]slope \: = \infty [/tex]
Slope is undefined.
Step-by-step explanation:
Slope m =
[tex] \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } [/tex]
(x1, y1) = (2,6) and (x2, y2) = (2,-9)
[tex]slope = \frac{ - 9 - 6}{2 - 2} [/tex]
[tex] = \frac{ - 15}{0} [/tex]
[tex] slope \: = \infty [/tex]
slope is undefined.
