The slope of any horizontal line on a graph is zero. That means that 'y' never changes, no matter how much 'x' changes.
Answer:
A) 
Step-by-step explanation:
Hi there!
The given equations are written in point-slope form:
where <em>m</em> is the slope of the line and
is a point that falls on the line
Notice how the line is travelling infinitely down as x increases. This means that the slope is negative.
Therefore, the equation of the line is either A or B.
Now, let's look at A:

This equation suggests that the point (4,-7) falls on the line, which it does.
Therefore, the equation of the graph is
.
