# Thread: Convert Vector equation into 2-point form equation

1. ## Convert Vector equation into 2-point form equation

Hi
I have problem solving (converting) vector equation into 2 point form.
I have found parametric equations but cant seem to get 2 point form.
x(t)= (1,0,-1)+t(3,1,-2)
my parametric form is....
x=1+3t....y=t......z=-1-2t

Can anyone give me some suggestions on how to get 2 point form. I dont need solution. Maybe someone can point me to some examples online.
Examples i have found use calculus to solve this but I cant use that.

Thank you

What is two point form?

3. ## it is....

I solved it...The form is actually (1-t)(p1,p2)+t(u1,u2)...

where t is scalar and p and u are points in 2d space...
