Persamaan garis h melalui(1,5) dan(a,3).gradien garis h adalah 3.nilai a dan persamaan garis h yaitu a. a=1/3, h: y=3x + 2 b. a=1/3, h: y=2x + 3 c. a=1/3, h: y=3x + 3 d. a=1/3, h: y=3x + 1

M = (y2-y1)/(x2-x1) m = (3-5)/(a-1) = 3 -2 = 3a - 3 3a = 1 a = 1/3 persamaan garis h melalui (1,5) dan m = 3 --> y = m (x-x1) + y1 y = 3(x-1) + 5 y = 3x -3 + 5 y = 3x + 2
m = (3-5)/(a-1) = 3
-2 = 3a - 3
3a = 1
a = 1/3
persamaan garis h melalui (1,5) dan m = 3
--> y = m (x-x1) + y1 y = 3(x-1) + 5
y = 3x -3 + 5
y = 3x + 2
