Step 1: Verify if the point (2,4) lies on the curve x^2 - xy - y^2 + 4 = 0. Substitute x=2 and y=4 into the equation: 2^2 - (2)(4) - 4^2 + 4 = 4 - 8 - 16 + 4 = -16 Since -16 ≠ 0, the point (2,4) does not lie on the given curve. For a tangent line to exist at a point, the point must be on the curve. Step 2: Make an assumption to proceed. We will assume there is a typo in the constant term of the curve's equation, and
