Temperature (°F), y 59 51 43 35 27 19 11

The y−intercept for this relationship is b = ???
Please help me! Thank you!

The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount during each of the three summer months. the store owner converts the frequency table to a conditional relative frequency table by row. which value should he use for x? round to the nearest hundredth. 0.89 0.90 0.92 0.96
