y – y1 = m (x – x1)
m =3 , x1 = -1 , y1 = -8
y+ 8 = 3(x + 1)                                                                                                                                y+ 8 = 3x + 3                                                                                                                         y - 3x = -5                                                                                                                                   -3x + y = -5
