[y-(-2)]/[x-(-4)] = -5
y+2 = -5x -20
y = -5x -22
What you just saw was using the point slope form in order to get the answer in to slope-intercept form (y=mx+b). M represents slope and b represents the y intercept (0,?). Slope is determined by dividing the rise or fall (vertical change) over the run (the horizontal change).
