1. If variable y depends on variable on x and increases as x increases, an increase would be shown on a graph by a diagonal line with points instead of lines. The line would start low and keep getting higher. In a table it'd be shown by a larger # every time in the y collum.

2. If variable y depends on variable x, and decreases as x decreases, a decrease would be shown on a graph by diagonal line with points instead of lines. The line would start high up on the graph and gradually decrease until it goes near the bottom. In a table it be shown by a fewer # every time in the y collum.

3. When there is a constant change then there would be straight lines on the graph.

4. It is appropriate to connect points in a graph when you are predicting data that is not currently on the graph.
