Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
Examples
- Starting at (0, 0) and moving 4 units right along the x-axis lands at (4, 0).
- The x-axis runs left to right through the origin.
Key rule
The x-value in an ordered pair tells how far to move along the x-axis.
Memory hook
X is x-tra flat — it runs side to side.
