(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Show that r1(t) and r2(t) define the same line, where

[itex]r_{1}[/itex](t) = <3,-1,4> + t<8,12,-6>

[itex]r_{2}[/itex](t) = <11,11,-2> + t<4,6,-3>

2. Relevant equations

3. The attempt at a solution

I set [itex]r_{1}[/itex](t) = [itex]r_{2}[/itex](t) and got the value of t which is 2.

then I plugged that t value into [itex]r_{1}[/itex](t) and [itex]r_{2}[/itex](t) which both of them came out to be <19,23,-8>. Is this how to do it?
