Compare the graphs of lines A, B, and C below.

1. Which line has the greatest slope? Justify your answer.

   Hint (a):

   Which line increases most sharply?

   Answer (a):

   Line A

2. What is the $y$-value of line A when $x = 2$?

   Hint (b):

   Locate line A and $x = 2$ on the graph.

   More Help (b):

   What is the $y$-coordinate of the point on the graph?

3. Compare the slopes of lines B and C.

   Hint (c):

   The lines are parallel. Parallel lines have the same change in $y$-axis for the same change in $x$-axis.
