Question

Persamaan Garis yang melalui titik (2,3) dan (-1,0) adalah?Tuliskan caranya!

Answer 1

(y-y1)/(y2/y1)=(x-x1)/(x2-x1)
(y-3)/(0-3)=(x-2)/(-1-2)
(y-3)/-3=(x-2)/-3
-3y+9=-3x+6
-3y+3x=6-9
-3y+3x=-3
-y+x=-1

Answer 2

(x₁ , y₁) = (2, 3)
(x₂ , y₂) = (-1, 0)

Persamaan Garis:
(y - y₁)/(y₂ - y₁) = (x - x₁)/(x₂ - x₁)
(y - 3)/(0 - 3) = (x - 2)/(-1 - 2)
(y - 3)/ - 3 = (x - 2)/- 3
y - 3 = x - 2
x - y + 1 = 0
