The table shows the cost in dollars to create CDs of digital photos at a photo shop. The table also shows this information as ordered pairs (number of CDs, cost in dollars).

Describe the pattern in the graph.

The points appear to be in a line.

Each point is one unit to the right

and 3 units up from the previous point.

The cost increases by \$3 for every CD created.
