6.NS.C.6b
Definition
Two numbers (x, y) that give the location of a point on the coordinate plane; order matters.
Examples
- (3, 2) means move right 3, then up 2.
- The x-value always comes first, the y-value second.
Key rule
Order matters — x comes first, y comes second.
Memory hook
Right/left, then up/down — in that order.
