We analyze the linear function to find that it has equation 
. Drawing the line, we find that it will intersect the circle at negative and positive x-coordinates.
We can prove this by substituting into the given equation:
Hence,
or 
, so there are both positive and negative values for 
.
We can prove this by substituting
Hence,
