Question 550350
Im unable to graph the equations on my TI-83! I must be doing something wrong! I am sorry that I was unable to post the pictures on here too! 
5. 
Match the correct graph with the given equation.
7x - y + 7z = 7 
6. 
Match the correct graph with the given equation.
2x - 3y + 3z = 6 

============
These must be graphed on a 3-dimensional coordinate system.
A TI-83 cannot handle that.
