5-44.

Find the slope of the line you would get if you graphed each sequence listed below and connected the points.

1.  $5,8,11,14,...$

• What is the common difference?

The points are $(1, 5), (2, 8), (3, 11), (4, 14), ...$
What is the constant rate of change? If in doubt, draw a graph.

• $m=3$

1.  $3,9,15 , \dots$

• See part (a).

1.  $26,21,16 , \dots$

• Remember that slopes can be negative.

• $m=−5$

1.  $7,8.5,10,...$

• See part (a).
