1)How does the graph of a system of equations differ from the graph of a system of inequalities?

2) When you solve a system of equations using elimination or subtitution,you will know what the system looks like based on the answer you get.Tell what the three possibilities look like and how you know.

inequalities are when the graph has the shaded are and the answer can be any point in that area.

a system of equations has only one answer or only one point where the two lines cross.

1.) The graph of a system of equation can result in 3 possible scenarios:
a.) A point if the two lines intersect.
b.)If the 2 lines are parallel, then the 2 lines never intersect or have a solution.
c.) If the 2 systems of equation represent the same line, then the will have infinitely many solutions.
Graphing a system of inequalities gives you shaded areas where the solutions are.  For example, the solution to an inequality can be above the line if it is greater than or below the line if it is less than.  If you have several inequalities to graph, then you must make sure all the shaded regions make each of the inequalities true.

2.) If the solution is something such as x=4 and y=6, then the solution is a point.
If the solution is something like 6=6, then this is always true so the 2 lines represent the same equation.
If the solution is like 4=2, this is never true so the 2 lines are parallel and never intersect.

1)Well systems of inequalities is basicly shaded area of a point and system of equations has a point where 2 lines intersect each other.

2)System of equations only effects with 2 equations that your doing whether if it's elimination or subtitution and I think 3 possibilities are right in the book
