Diketahui vector tunjukkan bahwa titik segaris (kolinier)

Diketahui vector begin mathsize 14px style straight K equals open parentheses table row 1 row 2 end table close parentheses comma space straight L equals open parentheses table row cell negative 2 end cell row cell negative 3 end cell end table close parentheses space straight M equals open parentheses table row 0 row cell negative 5 end cell end table close parentheses end style tunjukkan bahwa titik begin mathsize 14px style KLM end style segaris (kolinier)

  1. ...space 

  2. ...undefined 

Jawaban:

Titik begin mathsize 14px style straight K comma space straight L end style dan begin mathsize 14px style straight M end style dikatakan kolinier jika begin mathsize 14px style stack L M with rightwards arrow on top equals k times stack K L with rightwards arrow on top end style

Titik begin mathsize 14px style KLM end style segaris 

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell stack L M with rightwards arrow on top end cell equals cell k times stack K L with rightwards arrow on top end cell row cell straight M minus straight L end cell equals cell k times straight L minus straight K end cell row cell open parentheses table row 0 row cell negative 5 end cell end table close parentheses minus open parentheses table row cell negative 2 end cell row cell negative 3 end cell end table close parentheses end cell equals cell k times open parentheses table row cell negative 2 end cell row cell negative 3 end cell end table close parentheses minus open parentheses table row 1 row 2 end table close parentheses end cell row cell open parentheses table row 2 row cell negative 2 end cell end table close parentheses end cell equals cell k times open parentheses table row cell negative 3 end cell row cell negative 6 end cell end table close parentheses end cell end table end style 

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row 2 equals cell negative 3 k end cell row k equals cell fraction numerator 2 over denominator negative 3 end fraction end cell end table end style  

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell negative 2 end cell equals cell negative 6 k end cell row k equals cell fraction numerator negative 2 over denominator negative 6 end fraction end cell row k equals cell 1 half end cell end table end style 

Karena begin mathsize 14px style k end style tidak sama maka titik undefined tidak segaris.

Dengan demikian titik undefined tidak segaris.
