Question

Use the image to answer the question.

Four points are plotted on the first quadrant of a coordinate plane. The x-axis ranges from 0 to 10 in increments of 1 and the y-axis ranges from 0 to 17 in increments of 1. A line is drawn that almost passes through all the points.

Jazmin used a graphing calculator to graph a given dataset. She found that the trend line of her data is y=−0.694x+17.22
and that the correlation coefficient is −0.9153
. What conclusion should Jazmin make about the appropriateness of the linear model she found?

Based on the correlation coefficient of -0.9153, Jazmin should conclude that the linear model she found is a very strong fit for her dataset. The negative correlation coefficient indicates a strong negative linear relationship between the variables, which means that the linear model accurately represents the trend in the data points.
