An ellipse has its axes along the coordinate axes. If it passes through the point (4, -1) and is tangent to the line x + 4y - 10 = 0, then its equation is

1. x²/80 + y²/(5/4) = 1
2. x²/20 + y²/5 = 1
3. x²/100 + y²/5 = 1
4. Both (a) and (b)

Correct answer: Both (a) and (b)

Solution

Both options (a) and (b) represent valid equations of ellipses that satisfy the given conditions of passing through the point (4, -1) and being tangent to the specified line, confirming that they are both correct.
