We will use slope intercept form y=Mx+b M is slope and b is y intercept So you need a y intercept. Where does go thro the y axis? +1 From that point how much should you go down and right until you get to the graph again (this is the slope). Down 1= -1 and right 2= 2. So slope is -1/2
Now write it in the form Y=-1/2x + 1 is the answer
