Graphing
When graphing and the lines cross once...How many solutions are there?
One solution
The solution of the following system of equations:
4x + y = 15
y = 3
(3, 3)
The solution of the following system of equations:
3x-6y=3
4x+6y=32
What is "(5, 2)"?
When graphing and the lines do not touch and they are parallel, what type of solution is it?
No solution
The solution of the following system of equations:
y=-3
y=6x+3
What is "(-1,-3)"?
The solution of the following system of equations:
2x+8y=-22
x+5y=-12
What is "(-7, -1)"?
When graphing and the lines are the same, what type of solution is it?
Infinite Solutions
The solution of the following system of equations:
y=x-2
y=-2/3x+3
What is "(3, 1)"?
The solution to the system:
2x + 3y = 6
3x + 5y = 15
What is (-15, 12)?
What method would you use to solve this system
2x+3y=10
-2x+5y=12
Elimination
The solution of the following system of equations:
y=-3x
-3x+3y=0
What is "(0, 0)"?
The solution to the system
2a - 4b = 12
-8a + 16b = -48
