Step-by-step explanation:
Given two points with coordinates and
, the slope of the line passing through the two points is given by the equation
In this problem, the coordinates of the two points are:
and
which means:
Substituting all these values into the equation of m, we find the slope of the line:
The slope is infinite: this is because the line is vertical.
