Solution

Understanding the Problem

We are presented with a line, y=mx+73y = mx + 7\sqrt{3}, and a hyperbola, x224y218=1\frac{x^2}{24} - \frac{y^2}{18} = 1. The core information is that this line is normal to the hyperbola. Our task is to determine a possible value for the slope, mm, of this normal line. This problem is a classic application of the properties of hyperbolas, specifically the equation of a normal in slope-intercept form.
