A?

For the first question, notice that in the graph, all points on the line have a first coordinate of 2. No matter what the y-coordinate is, the x-coordinate is always 2. It's as if y doesn't matter at all. In fact, the equation is simply
x = 2
without y even being mentioned.
A vertical line has equation x = k, where k is the x-intercept and the x-coordinate of all points on the vertical line.

B
undeadknight26 (undeadknight26):
this is because it rests on the x axis...

A horizontal line has the same y-coordinate for all points.
The equation of a horizontal line is
y = k,
where k is the y-intercept and the y-coordinates of all points on the line.
