She used a graphing tool to display the data in a scatter plot, with x representing the temperature and y representing the inches of rain. Then she found the equation of the line of best fit
y = -0.424x + 31637
Based on the line of best fit, approximately how many inches of rain will fall in May if the average temperature is 48°F?
