Bab Persamaan Garis

(0, 2) dan (3, 4)

(y - y1) / (y2 - y1) = (x - x1) / (x2 - x1)
(y - 2) / (4 - 2) = (x - 0) / (3 - 0)
(y - 2)/2 = x/3
y - 2 = 2x/3
y = (2/3) x + 2
f(x) = (2/3) x + 2

Titik potong = (0,2) dan (3,4)

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y-2)/(4-2) = (x-0)/(3-0)

(y-2)/2 = x/3

y-2 =2/3 x

y = 2/3 x + 2

Jawabannya C. f(x) = 2/3 x + 2
