Homework Statement
Find parametric equations and symmetric equations for the line through the points (0,1/2,1) and (2,1,-3)
Homework Equations
The Attempt at a Solution
I started out graphing the points and connecting them with a straight line. I called the first point P and second Q. So the vector PQ = <2,1/2,-4>. So my vector r_0 is <0,1/2,1> so vector r = r_0 + tv
so <x,y,z>=<0,1/2,1> +t<2,1/2,-4>
<x,y,z> = <0+2t, 1/2 + t/2, 1-4t>
So my parametric equations are:
x=2t
y=1/2 + t/2
z=1-4t
And my symmetric eqs. are:
x/2 = 2y-1 = (z-1)/-4
This answer is wrong and I've done it a few times any hints? Thanks
