Gambarlah grafik persamaan garis berikut pada bidang koordinat.

b. size 14px y size 14px equals size 14px 4 size 14px x size 14px minus size 14px 1

Jawaban:

Kita akan mencari beberapa titik yang dilalui garis size 14px y size 14px equals size 14px 4 size 14px x size 14px minus size 14px 1.

Untuk begin mathsize 14px style x equals negative 1 fourth end style,

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row y equals cell 4 times open parentheses negative 1 fourth close parentheses minus 1 end cell row y equals cell negative 2 number space number space number space number space number space number space number space number space open parentheses negative 1 fourth comma space minus 2 close parentheses end cell end table end style

Untuk begin mathsize 14px style x equals 0 end style,

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row y equals cell 4 times open parentheses 0 close parentheses minus 1 end cell row y equals cell negative 1 number space number space number space number space number space number space number space number space left parenthesis 0 comma space minus 1 right parenthesis end cell end table end style

Dan untuk begin mathsize 14px style x equals 1 fourth end style,

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row blank blank y end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 4 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank times end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell open parentheses 1 fourth close parentheses end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank minus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 1 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank y end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 0 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank number space end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell open parentheses 1 fourth comma space 0 close parentheses end cell end table end style

Dengan menggambarkan ketiga pasangan titik pada bidang koordinat dan menghubungkannya dengan garis lurus, gambar grafik size 14px y size 14px equals size 14px 4 size 14px x size 14px minus size 14px 1 adalah
