6.1 Solving Systems by Graphing.
Learning Targets
1. Determine the number of solutions a linear system of equations has.
2. Solve a system of equations by graphing.
* Two or more equations form a system of equations.
* The ordered pair that is a solution of both equations is the
solution of the system.
* A system of two linear equations can have one solution, no
solution, or infinite solutions.
y=6
y = 2x + 4
y = 4x + 2
y = 3x
y = 2x + 1
2y = 4x - 6
y = 2x + 1
2y = 4x + 2
Post Assessment
Graph each system and solve.
y=x+5
y = ½x
y = -2x + 3
y = -x - 1
y-x=2
y = -2x - 8
