In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per acre). The data for a 9 year period is given in the table. The equation of the line of best fit for this data is y = 47.3 + 0.78x. How many bushels of wheat per acre can be predicted if it is expected that there will be 17 inches of rain?

Assuming x is the rainfall, you simply plug in 17 for x and solve for y.

47.3 +.78 (17)

= 47.3 + 13.26

= 60.56
