Answer:
Hi!
1) System of equations are two or more equations to be solved together involving a number of variables.
2) Graphs help us solve a system of equation by the solution of such a system that is the ordered pair that is a solution to both equations. (Hopefully that made sense)
3) A equation which has infinite solutions~
x-2y=3
2y=x-3
y=(1/2)x-(3/2)
x=0, y=-3/2
x=1, y=-1
x=-1, y=-2
and so on..
HOPE THIS HELPS!!
