Ex. 1 ~ Writing Ordered Pairs

Ex. 2 ~ Graphing Ordered Pairs

Ex. 3 ~ Graphing Multiple Ordered Pairs

Ex. 4 ~ Graphing and Solving for Ordered Pairs

Ex. 1 ~ Graphing Linear Equations

​ A)
y = -x + 3
y = 2x - 3





B)
y - 2x = 6
3y - 6x = 9

1. y = -3x + 1

y = x - 3
2. y = 2x + 3

-4x + 2y = 6

Ex. 2 ~ Substitution

Ex. 3 ~ Elimination

3x +7y = 15
5x + 2y = -4
