Question 329766
Solve the system of equations by graphing and then classify the system.
3x -9y = 36
2x -6y = -8
----------
Solve each equation for "y":
y = (1/3)x -4
y = (1/3)x + (4/3)
-------------------------- 
What would the graph look like and would this be inconsistent or consistent, dependent or independent?
---
The graph would be two parallel lines because the slopes are equal.
The system is inconsistent because there is no x/y pair that 
satisfies both equations.
