Explanation Slide...

Start by identifying where the graphed line crosses the y-axis - this is the "b" or "begin" value of the graph, b = 1. Next, determine the slope or "move" value between 2 points. Here the move value is up 2 left 1, making the slope value -2/1 or m = -2. The equation is y = -2x +1.
