If anyone could explain how the following is done without a grapher, it would be greatly appreciated:
Determine if the two lines A and B are parallel, skew, or intersecting. If they are intersecting, find the point at which they intersect.
A: x = 13 + 12t, y = -7 + 20t, z = 11 - 28t
B: x = 22 + 9s, y = 8 + 15s, z = -10 - 21s
Hello, meebo0129!
Determine if the two lines A and B are parallel, skew, or intersecting.
If they are intersecting, find the point at which they intersect.
The direction vector of is: .
The direction vector of is: .
. . Therefore: .
The point is on line .
. . Is it on line ?
We have: . . . . . Yes!
Therefore, lines and are coincident.
