There are a few different ways to visualize that relationship.  Here
is the most obvious one:

ContourPlot[8 x - x^2 + 14 y - y^2 == 49, {x, -10, 15}, {y, -10, 15}]


Also try something like this:

RadiusList = {25, 36, 49};
ContourPlot[
 8 x - x^2 + 14 y - y^2 == RadiusList, {x, -10, 15}, {y, -10, 15}]


ContourPlot has lots of fun options - browse the help files. (Right-
click on "ContourPlot" and choose "Get Help."
