Homework Statement
Solve the following systems and interpret the result geometrically3x + 4y + 5z - 18 = 0
2x - y + 8z - 13 = 0
-x + 17y + 25z + 11 = 0
A line of intersection of 3 planes is the line that exists where all 3 planes intersect. This line is formed by the points that are common to all 3 planes.
If the equations of the 3 planes have a single unique solution, then they intersect at a single point. If the equations have infinite solutions, then the planes intersect at a line. This can be determined by solving the system of equations using methods such as substitution or elimination.
No, a line of intersection of 3 planes cannot be parallel to any of the planes. This is because if a line is parallel to a plane, it would not intersect the plane at any point, which contradicts the definition of a line of intersection.
A line of intersection of 3 planes can be uniquely defined by two points. These two points are the intersection of the line with any two of the three planes.
Yes, it is possible for 3 planes to intersect at more than one line of intersection. This occurs when the planes are not all parallel to each other, and the lines of intersection are not parallel to each other either.
