How do you know if a trend is linear?
We interpret the slope to mean that, on average, the rate changed by the slope value each year. The issue is whether the slope value is significantly different from zero, i.e., is the P-value less than or equal to 0.05. If it is, we have a linear trend. If it is not, we must conclude there is no meaningful trend.
