Please help with question 1 

{{x, y) : x² – xy + y² = 7} where the tangent line to C is
1. Find all points on the curve C =
PERPENDICULAR to the line with equation y = 3x – 1.
2. Consider the famous 3D surface where x2 + y² + z² = a + 1. Explain, by using Theorem 105,
why the surface has a tangent plane at any point on this surface.
