Answer:
Step-by-step explanation:
Use the midpoint formula:
So, the Change In X is 2-8 = -6
And the Change in Y is 7-4 = 3
Once you divide both of the changes by 2, you get
X: -3
Y:
So the midpoint is:
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,
