A trend chart had the variable YEAR on the X-axis. Values for the variable YEAR were 1990, 2000, 2005, 2010, and, 2015. The tick marks on the axis should be spaced equally to reflect the true slope of the trend line.

The tick marks for the years 1990, 2000, 2005, 2010, and 2015 should be spaced according to the time intervals they represent to accurately reflect the passage of time and the true slope of the trend line. Since the intervals between these years are not equal (10 years, 5 years, 5 years, 5 years), equal spacing would inaccurately represent the time intervals.
