For what ordered pair (a,b) are there infinite solutions (x,y) to the system

4x + ay = -8

2x - 3y = b

4x + ay  =  -8   --->     4x + ay  =  -8

2x - 3y  =  b     --->     4x - 6y   =  2b

 

Choose a = -6  and  b  =  -4

 

Then, you have two equivalent equations:  4x - 6y  =  -8

                                                                     4x - 6y  =  -8
