garis yang melalui titik (-4,3) dan b(5,-2)
![]()
Materi : Persamaan Garis Lurus
Titik ( x¹ = -4 dan y¹ = 3 )
Titik ( x² = 5 dan y² = -2 )
\__________________/
y - y¹ / y² - y¹ = x - x¹ / x² - x¹
( y - 3 )/( - 2 - 3 ) = ( x + 4 )/( 5 + 4 )
( y - 3 )/(-5) = ( x + 4 )/(9)
9( y - 3 ) = -5( x + 4 )
9y - 27 = - 5x - 20
9y + 5x - 7 = 0
Semoga bisa membantu
