Jazmin should conclude that the linear model is appropriate for her dataset since the correlation coefficient of -0.9153 indicates a strong negative linear relationship between the variables. The negative slope of the trend line further reinforces this relationship, suggesting that as one variable increases, the other decreases predictably.
