Determine which system below will produce infinitely many solutions. (2 points)


1) -4x + 6y = 20   

    4x - 3y = -2


2) -2x + 4y = 18   

     4x - 8y = -36


3) 3x - 2y = 5         

   -6x - 4y = -10


4) 5x - 3y = 12       

    15x - 9y = 24

the answer is 2) -2x + 4y = 18   &  4x - 8y = -36 
This is because they are the same line and therefore have infinite solutions...
The first equation is multiplied by -2 to get the second equation
