To find the equation of the normal line to the circle (x^2 + y^2 = 25) at the point (4, 3):

- Find the derivative of the equation of the circle with respect to (x).
- Evaluate the derivative at the point (4, 3) to find the slope of the tangent line.
- Find the negative reciprocal of the slope to get the slope of the normal line.
- Use the point-slope form of a line to find the equation of the normal line using the slope found in step 3 and the point (4, 3).
