persamaan garis yang melalui titik (2,1) dan (3,6) adalah

y1 = 6
y2 = 1
x1 = 3
x2 = 2

[tex]Rumus \\\\y \ - \ y_{1} \ = \ ( \frac{ y_{1} \ - \ y_{2} }{ x_{1}\ - \ x_{2} }) (x \ - \ x_{1} ) \\\\ y \ - \ 6 \ = \ ( \frac{6 \ - \ 1}{3 \ - \ 2} ) (x \ - \ 3) \\\\ y \ - \ 6 \ = 5 \ (x \ - \ 3) \\\\ y \ - \ 6 \ = \ 5x \ - \ 15 \\\\ y \ = \ 5x \ - \ 15 \ + \ 6 \\\\ y \ = \ 5x \ - \ 9 \ =\ \textgreater \ \ (Dalam \ bentuk \ y \ = \ ax \ + \ c) \\\\ -5x \ + \ y \ + \ 9 \ = \ 0 \ =\ \textgreater \ \ (Dalam \ bentuk \ ax \ + \ by \ + \ c \ = \ 0 )\\\\ Jika \ membantu, \ Jadikan \ Jawaban \ Terbaik[/tex]
