The line through (4,6)(4,6) and (4,8)(4,8) has an "undefined" slope.

Explanation:

This is a vertical line; there is no change in the xx coordinate value;
and since the slope is defined to be ("change in "y)/("corresponding change in "x)change in ycorresponding change in x any attempt to evaluate the slope would result in an attempt ot divide by zero.
