Answer:

Step-by-step explanation:
First plug the equation of y into the equation of z, so that we get their intersection:
We plug

Into: 
So, we get:

Then we set
And plug that in the equation
and the one we just got for z.
So that we get:

Therefore, the vector function that represents the curve of intersection is:
