Systems of Equations
Create a graph of a system of equations with ONE SOLUTION
Two lines where the line crosses ONCE.
y=2
x+y=7
Write your answer as an ordered pair.
(5,2)
x + y = 9
x - y = 1
(5,4)
y = -4
x = 2y + 4
Substitution
What continent is Egypt located?
Africa
Create a graph of a system of equations with NO SOLUTION.
A graph where the two lines are parallel.
x=3y
x - 2y = 12
(36,12)
2x + y = 8
2x - y = 4
(3,2)
y = 3x +4
y = x - 6
Graphing OR Substitution
What part of the cell is known as the control center?
Nucleus
Create a graph of a system of equations with INFINITELY MANY SOLUTIONS.
A graph where the lines are on top of each other.
y = 2x - 2
x - 2y = 10
Write as an ordered pair.
(-2,-6)
2y + 7x = -5
5y - 7x = 12
(-1,1)
2x + 3y = 100
6x - 3y = -12
Elimination
What document ended World War 1 and crippled Germany as a country?
Treaty of Versailles
When solving a system of equations in this class, you will always have ______ variable (s)
2
2y = 8x - 4
3x + y = 11
(2,5)
3x + 2y = 12
x + 2y = 8
(2,3)
2y + x = 10
y - 4x = 0
