9.62.* A study by the National Highway Traffic Safety Administration estimated that 73% of people wear seat belts, that failure to wear seat belts led to 9200 deaths in the previous year, and that that value would decrease by 270 for every 1 percentage point gain in seat belt usage.

Let ˆy = predicted number of deaths in a year and x = percentage of people who wear seat belts. Find the prediction equation that yields these results.
