Tentukan gradien garis yang menghubungkan pasangan titik: a.A (3,1) dan B (7,9) B.P (4,7)dan Q (2,-1) c.R (-2,3) dan S (4,-5) plisd ka buat bsk tlng diJwb
Rumus mencari gradien jika diketahui 2 titik m= (y2-y1) / ( x2-x1) a) (3,1) (7,9) m= ( 9-1) / (7-3) m = 8 /4 m = 2 b) m= (-1 -7)/ (2-4) m = -8 / -2 = 4 c) m = (-5 -3) /(4-(-2)) m = -8 / 6 m = -4/3

Rumus mencari gradien jika diketahui 2 titikm= (y2-y1) / ( x2-x1)
a) (3,1) (7,9)
m= ( 9-1) / (7-3)
m = 8 /4
m = 2
b) m= (-1 -7)/ (2-4)
m = -8 / -2
= 4
c) m = (-5 -3) /(4-(-2))
m = -8 / 6
m = -4/3
