A company tracks its monthly revenue over the past 12 months. The data (in thousands of dollars) is as follows:	
	
Month	Revenue ($)
January	48
February	55
March	60
April	62
May	65
June	72
July	73
August	71
September	74
October	80
November	82
December	88
	
The goal is to identify whether there is a linear trend in the revenue over time and	
 forecast future revenue for the next few months.
