Question 478367: Solve each system graphically. Be sure to check your solution. If a system has an infinite number of solutions, use set−builder notation to write the solution set. If a system has no solution, state this.
6x − 2y = 2,
9x − 3y = 1

Solve each system graphically. Be sure to check your solution. If a system has an infinite number of solutions, use set−builder notation to write the solution set. If a system has no solution, state this.
6x − 2y = 2,
9x − 3y = 1
------------
Multiply 1st equation by 3.
Multiply 2nd equation by 2.
18x - 6y = 6
18x - 6y = 2
---
Subtract to get:
0 = 4
----
That is a contradiction indicating the
system does not have a solution.

Graphing will show the two lines are parallel:
