Edexcel also uses the vocabulary “explanatory” for independent x and “response” for dependent y

Though of course it may not be actually dependent!

In CP1 you specifically have to find the normal to a plane containing 2 given vectors, which you can do as a.n=0 and b.n=0 and solve simultaneously (again assuming a value for one of x,y, z) but doing it from the normals of 2 given planes and finding a common point is a lot more work!

DO. IT.

Oh, I can't find it. Can you do a screenshot sometime? Thanks

Edexcel FP1 exercise 1E question 3 page 23

Yes in Further Maths

The direction of the line is perpendicular to both normals, so this would be in FP1 not CP1

And they just have to find any point that lies in both, ie solve the two plane equations simultaneously assuming a specific value for one of x, y, or z
