Tolong donk kaka beaok di kumpulin nih pllllllliiiiiizizziziziz​

Answer 1

gradien garis yang melalui titik (-2, 3) dan (4, -1)

m = (y2 - y1) / (x2 - x1)

m = (-1 - 3) / (4 - (-2))

m = (-4)/6

m = -2/3

Karena tegak lurus, maka :

m1 . m2 = -1

-2/3 . m2 = -1

m2 = 3/2

Melalui titik (2, -5)

Persamaan garis

y - y1 = m(x - x1)

y - (-5) = 3/2(x - 2)

2(y + 5) = 3(x - 2)

2y + 10 = 3x - 6

3x - 2y - 6 - 10 = 0

3x - 2y - 16 = 0
