The slope of a line passing through two points is the ratio between the difference of the y coordinates and the difference of the x coordinates. In formulas, you have
If you plug your values, you have
which is undefined.
In fact, since the two points share the same x coordinate, the segment AB is vertical, and the slope is not defined for vertical lines.

ANSWER
Boundary line: dashed line.(not a solid boundary line)
Shading: We shade the upper half-plane.
EXPLANATION
The given inequality is
To graph this inequality, we graph the corresponding linear equation.
This is what we called the boundary line.
Since the inequality sign does not have an equal sign against, it means the boundary line is not inclusive.
This means that any point on the boundary line will not satisfy the inequality.
So we use a dashed line for the boundary line of this inequality.
We then test to see if the origin satisfies the inequality, because the boundary line is not passing through the origin.
This statement is true, so we shade the upper half plane.

You might wanna double check though just incase.
