Graph Ordered Pairs
Date
An ordered pair is two numbers that tell you where a point is on a grid.
• The center point of a grid is (0, 0)
• The first number in the pair tells you where on the x-axis the
point is. This is how far left or right you go on the grid. Negative
numbers are left. Positive numbers are right.
• The second number in the pair tells you where on the y-axis the
point is. This is how far up or down you go on the grid. Negative
numbers are down. Positive numbers are up.
