Quizplus · Accepted Answer

The data points in the graph show a clear, steady increase or decrease over time, indicating a linear trend. There is no indication of a quadratic curve or a repeating pattern like a cosine wave. There is also no evidence of a rapid change in direction or a curve that approaches a constant value, ruling out the tangential and flat trends, respectively.
