An equation for the ellipse ( standard form ):
x²/a² + y²/b² = 1
Here is: a - semi-major axis and b - semi-minor axis.
Radius of the moon is 1,000 km and the distance from the surface of the moon to the satellite varies from 953 km to 466 km.
a = 1,000 + 953 = 1,953 km
b = 1,000 + 466 = 1,466 km
Answer:
The equation is x² / 1,953² + y² / 1,466² = 1
or: x²/3,814,209 + y²/2,149,156 = 1
slope (m) = (y₂ - y₁)/(x₂ - x₁)
-2/1 = (a - 1)/(5 -(-5))
-2 = (a - 1)/10
-20 = a - 1
-19 = a
Answer: a = -19
