If: y = -8 -3x and y = -2 -4x -x^2

Then: -8 -3x = -2 -4x - x^2

Transposing terms: x^2 +x -6 = 0

Factorizing: (x-2)(x+3) = 0 => x = 2 or x = -3

Points of intersection by substitution are at: (2, -14) and (-3, 1)

Where are the points of contact when the line 3x -y equals 5 passes through the curve 2x squared plus y squared equals 129?

It works out that line 3x-y = 5 makes contact with the curve 2x^2 +y^2 = 129 at (52/11, 101/11) and (-2, -11)


What if a right circular cone intersects a plane that passes through one of its nappes but the plane is not parallel to an edge of the cone?

Then the intersection is a hyperbola.


What is the intersection of a line and a plane?

The intersection of a line and a plane can result in either a single point, if the line passes through the plane, or no intersection at all if the line is parallel to the plane and does not touch it. In some cases, if the line lies entirely within the plane, every point on the line will be an intersection point. Thus, the nature of the intersection depends on the relative positions of the line and the plane.
