x + 2y = 1 5 a2 ch 3 3.1 notes.notebook September 26, 2013 Ex: Solve the system graphically.
2x + 4y = 12
x + 2y = 6
• 1st equation • 2ND equation What does this mean?
the 2 equations are for the same line!
• Infinitely many solutions Ex: Solve graphically: x – y = 5 2x 2y = 9
• 1st equation:
Solve for y • 2nd equation:
Solve for y • What do you notice about the lines?
• They are parallel! Go ahead, check the slopes! • No solution! 6 a2 ch 3 3.1 notes.notebook September 26, 2013 7...
