Yoshi wants to add the line
to her graph. Predict where it would lie and sketch a graph to show its position. Justify your prediction.
The slope of the line in part (c) is the opposite of the slope of the line in part (b). The
-intercepts are the same.
Where would the line
lie? Again, justify your prediction and add the graph of this line to your graph.
