Question

The latusrectum of the parabola y² - 2x - 6y + 5 = 0 is

• A. 1
• B. 2
• C. 4
• D. 6

Answer 1

Answer: (B)

2

Answer 2

We know that the length of the latusrectum of the parabola λx = ay² + by+c is$\left| \frac{\lambda}{a} \right|$.

∴ The length of latusrectum of the parabola 2x = y² – 6y + 5 is $\left| \frac{2}{1} \right|$= 2.
