Tentukan persamaan garis (-3,6) (2,4)

( y - y1) / ( y2 - y1) = ( x - x1) / ( x2 - x1)
( y - 6) / ( 4 - 6 ) = ( x + 3) / ( 2 + 3)
( y - 6) / ( - 2) = ( x + 3) / 5
5 ( y - 6 ) = (-2) ( x + 3)
5y - 30 = - 2x - 6
5y + 2x = 30 - 6
5y + 2x = 24

Persamaan garis melalui (-3, 6) dan (2, 4)
x₁ = -3
y₁ = 6
x₂ = 2
y₂ = 4

Persamaan garis
(y - y₁) / (y₂ - y₁) = (x - x₁) / (x₂ - x₁)
(y - 6) / (4 - 6) = (x - (-3)) / (2 - (-3))
(y - 6) / (-2) = (x + 3) / 5
5(y - 6) = -2(x + 3)
5y - 30 = -2x - 6
5y = -2x - 6 + 30
5y = -2x + 24
2x + 5y - 24 = 0
