## Homework Statement

The question is attached in the picture.

## The Attempt at a Solution

I have found the direction vector of the intersection line, but I have yet to find a point that lies on both planes...

I've thought about having [itex]\hat{m}[/itex] and [itex]\hat{n}[/itex] as basis vectors, but i still lack 1 more vector as this question is in 3 dimensions..

OR

Since I am restricting the point to lie only on the line it can be considered as 2 dimensions?

and hence a = x[itex]\hat{m}[/itex] + y[itex]\hat{n}[/itex] ??

Then I can plug into the 2 plane equations and solve for x and y.
