Step 1 of 10
Start
Read x first, then y.
Read one point
(1, 3)
(0,1), (1,3), (2,5), (3,7), (4,9)
(0,10), (2,8), (4,6), (6,4)

Rising line
Each ordered pair marks one point.
x = 1 first
(1, 3)
y = 3 next
Same move
RIGHT 1
UP 2
x: +1 each point | y: +2 each point
Repeat +1, +2
4 + 1 = 5 | 9 + 2 = 11
Next point: (5, 11)
Falling line
The same move can point down.
Same move
RIGHT 2
DOWN 2
Repeat +2, −2
6 + 2 = 8 | 4 − 2 = 2
Next point: (8, 2)
Your turn
Find one repeated move.
Find the step. Then extend.
Show your work.
Find the step and next point.
Nice work!
Same move
RIGHT 1
DOWN 2
x: +1 each point | y: −2 each point
Repeat +1, −2
3 + 1 = 4 | 2 − 2 = 0
Next point: (4, 0)
