X= temperature 65, 60, 55, 50, 45, 40, 35, 30, 25

y= cups sold per hr 8, 10, 11, 13, 12, 16, 19, 22, 23

My equation is y = -03833x + 32.139

r^2 = 0.9464

r = 0.974372

I have a negative trendline

My question is Can I use the regression equation to predict the number of cups of coffee sold per hour when the temp is 52 degrees and when its' 95 degrees? Why or Why not? I think I can but I don't know he equation I would use. can someone help me figure it out?

Thanks
