For what ordered pair (a,b) are there infinite solutions (x,y) to the system
4x + ay = -8
3x - y = b
If the equations are the same...there is infinite solutions ...they are the same line...
multiply bottom equation by 1 1/3
4x - 1 1/3 y = 1 1/3 b then if a = - 1 1/3 and 1 1/3 b = -8 b = -6 the equations become the same
