Question

Tentukan persamaan linier yg melalui titik berikut ini:
a) (3,4) dan (6,0)=......
tolong bantu dongk...

Answer 1

Gunakan rumus persamaan garis melalui dua titik.
(y-y1) / (y2-y1) = (x-x1)/(x2-x1)
titk (x1,y1) = (3,4)
titk (x2,y1) =(6,0)
.
(y-4)/(0-4) = (x-3)/(6-3)
(y-4) / (-4) = (x-3)/(3)
3(y - 4) = -4(x-3)
3y -12 = -4x + 12
4x + 3y = 24
atau
4x + 3y - 24 = 0
