Barrett used Desmos for the following data set and says that the slope of the line of best fit is −0.236.
Wallace, without looking at Barrett's work or performing any calculations, says that Barrett's answer is wrong. How does Wallace know that Barret is incorrect?

From the table, it can be seen that there is a positive relationship, so the slope of the line of best fit must be positive.

From the table, it is clear that the y-intercept would be positive. Barret's line would have a negative intercept because the slope is negative.

The data in the table has a quadratic relationship, so there would not be a line of best fit.
