Answer:

(x-1)²/49 + (y+3)²/16.51 = 1

Explanation:

vertex (8,-3) Foci (6.7,-3) center (h,k) = (1,-3) , major axis parallel to x axis

a is the distance of the vertex from the center, and c is the distance of the foci from the center. b is semi-minor axis

b² = a² - c² Ellipse equation: (x-h)²/a² + (y-k)²/b² = 1

a = 8-1 = 7 c = 6.7 - 1 = 5.7

b² = 7² - 5.7² = 16.51

Ellipse equation: (x-1)²/49 + (y- -3)²/16.51 = 1 i.e. (x-1)²/49 + (y+3)²/16.51 = 1
