#### Problem Statement: CE Board May 1995

What is the equation of the normal to the curve x^2 + y^2 = 25 at (4, 3)?

Note: The slope of the line normal to the curve at the given point is equal to the negative of the reciprocal of the slope of the given curve.

- A. 5x + 3y = 0
- B. 3x – 4y = 0
- C. 3x + 4y = 0
- D. 5x – 3y = 0

#### Problem Answer:

The equation of the normal to the curve is equal to **3x – 4y = 0**
