Materi : Persamaan Garis Lurus
Titik ( x¹ = 2 dan y¹ = 3 )
Titik ( x² = 1 dan y² = 4 )
\_________________/
m = ( y² - y¹ )/( x² - x¹ )
m = ( 4 - 3 )/( 1 - 2 )
m = 1/(-1)
m = -1
Titik ( x¹ = 0 dan y¹ = 2 ) dan m = -1
keterangan : Sejajar ( m )
\__________________________/
y - y¹ = m( x - x¹ )
y - 2 = - ( x - 0 )
y - 2 = - x
[ x + y = 2 ]
Semoga bisa membantu
