Pet Math Problem.png

I got this to be my answer: y=-.802x+1632.889

Use the regression equation from the previous problem (with constants rounded to three decimal places) to estimate the percentage of households in the United States that had a dog for a pet in 1989 and in 1999. Round the answers to one decimal place. Do not include a percent sign.

For 1989 I got 37.7 as my answer

For 1999 I got 29.7 as my answer

I’m not sure if my answers are correct and I know if the equation is not right then the other answers will be wrong. Please check and let me know. Thank you!
