Question

determining the purpose of a linear trendline
what is the purpose of a linear trendline?
○ graphically represent trend of current data and predict the future of a steady rate
○ graphically represent trend of current data rate in an up-down trend
○ graphically predict the future of an up-down rate
○ graphically represent trend of current data and predict the future of a sporadic rate

Explanation:

A linear trendline is used to show a straight - line relationship, meaning a steady rate of change. It both represents the trend of existing data and can predict future values when the rate is steady (linear). The second option's "up - down trend" is non - linear, the third's "up - down rate prediction" is incorrect for linear, and the fourth's "sporadic rate" is not steady, so the first option is correct.

Answer:

A. graphically represent trend of current data and predict the future of a steady rate
