Question

Tentukan persamaan garis p(4,3) dan bergradien 2/3

Answer 1

Mencari persamaan garis
y - y1 = m(x - x1)

y - 3 = 2/3 (x - 4)
y - 3 = (2/3)x - 8/3
y = (2/3)x - 8/3 + 3
y = (2/3)x - 8/3 + 9/3
y = (2/3)x + 1/3

Answer 2

Y - 3 = 3/2 (x - 4)
y - 3 = 3/2x - 6
     y = 3/2x - 6 + 3
     y = 3/2x - 3
