Thanks a lot:)

So would the equation for the new equation be (x,y,z)=(2,3,-1)+s(5, 2, -1) + t(3, -2, 4).

Homework Statement Determine vector and parametric equations for the plane containing the point A(2, 3, -1) and parallel to the plane with equation (x, y, z) = (2, 1, -3) + s(5, 2, -1) + t(3, -2, 4). Show your work. Homework Equations Vector and parametric This a strange equation that I...

Is that right?

Ok I kind of understand it now. This is what I have so far x1,y1=kx2,ky2 (x1,y1)/(k,k)=(kx2,ky2)/(k,k) (x1,y1)/(k,k)=(x2,y2)

By writing as two equations do you mean as in... 1.(x1,y1) 2.(kx2,ky2) Eliminate k. The only way I can think for eliminating k is kx2,ky2=0 kx2,ky2/k=o/k x2,y2=0 I don't know if I'm doing this right.

You said I should write out 2 equations: (x1,y1)=k(x2,y2) x1,y1=kx2,ky2 Is that right?

So this is the final answer?

So I did that I got (x1, y1)/x2, y2)=k

I wrote a=kb in coordinates. I don't if I did it correctly. x1y1=k(x2y2) x1k1/x2y2=k Is that all i need to do?

So if I use a=kb will I have to find the constant. Looking at the equation I'm trying to prove, do I have to to find out what y and x( the x and y without the number)?

Would I use a.b to prove that is it parallel?

OK so I call a point P. I don't know what you mean about those two vectors. Would I have to find the m which is the slop and then n which is the normal point. Looking at my notes none of this makes sense:confused:

With the piece that goes in the ground. The problem didn't come with a diagram because so you have to come up with your own.
