Question

Equation + = 1 represents:

• A. Circle
• B. A parabola
• C. An ellipse
• D. Hyperbola

Answer 1

Answer: (B)

A parabola

Answer 2

Here, += 1

Squaring both sides, ax + by + 2= 1

or 2= (1 – ax – by) again squaring

4abxy = 1 + a²x² + b²y² –2ax – 2by + 2abxy

a²x² + b²y² – 2abxy –2ax – 2by + 1 = 0

which is clearly as parabola.
