(Change in y)/(change in x)=(9--5)/(3-3)=14/0
Anything /0 is undefined. This line's slope is undefined.
You can also see this from the graph of the line. It is vertical. Any vertical line has undefined slope. Any horizontal line has a slope of 0.

slope is (change in ) / (change in )

The slope is infinite because there is no change in from
one point to the other and the line through the points is vertical
