Where does this line cross the y-axis?  Answer:  at (0, -1).  This is your y-intercept (b).
                                                        rise       -4 - 2
What's the slope of this line?  m = ------- = ----------- = -3
                                                         run       1 - (-1)

Thus, the equation of this line is y = -3x - 1.
