Marta’s equation has a positive y-intercept, but the scatterplot shows a negative correlation.
<h3>What is a scatter plot?</h3>The scatter plot is a manner in which data is presented as dots on a cartesian axes, The line of best fit is a description of the data that is presented in the scatter plot.
Hence, Marta is incorrect because Marta’s equation has a positive y-intercept, but the scatterplot shows a negative correlation.
