How is graph paper helpful in working with maps?

The grid helps to determine location.

Define a horizontal line.

A line that runs right to left or back and forth.

How does joining two perpendicular number lines help you locate a point on a map?

Values in two dimensions give more precise location information than just one value.

Why does the order in an ordered pair matter?

It tells me that first I need to 'go right x units and then up y units.' If I 'go right y units and then up x units,' this is a completely different location.

How can connecting the points on a graph of a real-world situation help us?

It helps us to see patterns and trends.
