At the given point,

Then the level curve is

which is a circle centered at the origin with radius 5 - quite easy to sketch.
Answer:
Non linear( it doesn't go through the 0
Step-by-step explanation:
Answer:
(x-4)²/16 + (y-8)²/25 = 1
Step-by-step explanation:
center (h,k): ((4+4)/2 , (3+13)/2) = (4 , 8)
a = 13-8 = 5 c = 8-5 = 3
b = √5²-3² = 4
Equation: (x-h)²/b² + (y-k)²/a² = 1
(x-4)²/16 + (y-8)²/25 = 1
G= -36
