Find direction numbers for the line of intersection of the planes x + y + z = 7 and x + z = 0. (enter your answers as a comma-separated list.)

We have given equation of planes as

Plane 1:

Plane 2:

That is

Line direction numbers is

× = ×

=

Therefore direction numbers for the line of intersection of the planes and is.

The line of intersection has a direction vector that is the cross product of the normal vectors of the given planes.

... [1, 1, 1] × [1, 0, 1] = [1, 0, -1] . . . . . . using a suitable calculator

The direction numbers of the line of intersection are (1, 0, -1).

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
