SOLUTION: Which system of equations below has infinitely many solutions? y = �3x + 4 and y = �3x � 4 y = �3x + 4 and 3y = �9x + 12 y = �3x + 4 and y = �6x + 8

Question 930370: Which system of equations below has infinitely many solutions?
y = �3x + 4 and y = �3x � 4
y = �3x + 4 and 3y = �9x + 12
y = �3x + 4 and y = �6x + 8
Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
y = �3x + 4 and 3y = �9x + 12
---
(3y = �9x + 12)/3 = y = �3x + 4
---
the two equations are for the same line
