Consider these two equations:  

$y=3x−2$
$y=4+3x$

1. Graph both equations on the same set of axes.

2. Solve this system using the Equal Values Method.

   Hint (b):

   Set the equations equal to each other and solve for $x$. What do you notice?

3. Explain how the answer to part (b) agrees with the graph you made in part (a).
