The order in which you name a point is
important which is why the coordinates of
ordered pair
the point are called an ______________.

EXAMPLE 1:
Determine the quadrant and coordinates for
points A, B, C, D, E, F, G, H, and I on the graph.

Sometimes when we talk about a set of ordered
pairs we make a table to show the values of x and y.
