I know how to do it using one equation but I am unsure about how to do it using two equations

Thanks

Could you please show an example I cant find anything about tangent vectors in my book

Thanks

My class has not learned anything about using derivatives with vectors is there another way to solve this without using derivatives?

thanks

What textbook are you using?

I think its better for me to take a look at it to see what tools you have at hand.

(x,y,z)=(-1/2,-1/2-5/2)+t(1/2,1/2,1)

and

(x,y,z)=(-1,0,0)+s(1,3,-1)

would I have to combine these?

Good. Now those constant vectors which are the coefficients of t and s are the tangent vectors to those lines. Now you can either take the vector product of those tangent vectors as the tangent vector for your line or consider a vector with unknown components and set its scalar product with both tangent vectors to zero and find the components and take it as the tangent vector for your line.
