Find the slope of the line through the pair of points. A(2, –3), P(2, 9)

Flauer [41]

The slope: $m=\dfrac{y_2-y_1}{x_2-x_1}$

$A(2;-3)\to x_1=2;\ y_1=-3\\P(2;\ 9)\to x_2=2;\ y_2=9\\\\subtitute:\\\\m=\dfrac{9-(-3)}{2-2}=\dfrac{12}{0}!!!$

The denominator can not be zero!

Conclusion: The slope is undenfined.
