ContourPlot[
 8 x - x^2 + 14 y - y^2 == 49,
 {x, -2, 10}, {y, 1, 13}]

Plot[y /.
  Solve[8 x - x^2 + 14 y - y^2 == 49, y],
 {x, 0, 8},
 Frame -> True,
 Axes -> False,
 PlotRange -> {{-2, 10}, {1, 13}},
 AspectRatio -> 1]

RegionPlot[8 x - x^2 + 14 y - y^2 > 49,
 {x, -2, 10}, {y, 1, 13}]

=============
I am new to Mathematica and going at snail's pace.
I would like to plot:

8x - x^2 + 14y - y^2 = 49

Anyone?
