We see that the slope of this line is so we plug this and the point
into the point-slope form
(note that there's nothing special about the point I picked; you can choose any point on the line):
This rearranges to the slope-intercept form
First, note that 
is always positive (except for x=0), so 
must be always negative.
Thus, the only plausible graphs are 1 and 3 since they are below the x-axis.
Now, and are only defined for x≥0, because only for these x'es we can take the square root.
Note that the third graph has domain (-infinity, 0], so it is not the right one, while 1 is ok.
Answer: first graph
