Homework Statement
Find a parametrization of the vertical line passing through the point (7,-4,2) and use z=t as a parameter.
Homework Equations
r(t) = (a,b,c) + t<x,y,z>
The Attempt at a Solution
I used (7,-4,2) as (a,b,c) (the point) and used <0,0,1> for the vector since it had to be vertical and got the components to be
x=7
y=-4
z=2+t
