1: name 3 methods for solving equations.
2: if a system has no solution, how does it look on a graph?
3: describe the characteristics of a graph when systems of equations have infinitely many solutions.
4: identify the solution to a system of equations for a graph.

1- The Substitution Method, Addition Method and Graphing method

2- The system is graphed as parallel lines, no interception between equations

3- One of the graphed lines is merged inside the other, it appears that an equation is missing.

4- The equations are graphed showing a common interception.
