The results of the regression were:y=ax+b a=-1.144 b=35.462 r2=0.765625 r=-0.875

Use this to predict the number of situps a person who watches 9 hours of TV can do (to one decimal place)

A regression was run to determine if there is a relationship between hours of TV watched per day (x) and
number of situps a person can do (y).
The results of the regression were:
y=ax+b
a=-1.144
b=35.462
r²=0.765625
r=-0.875
Use this to predict the number of situps a person who watches 9 hours of TV can do (to one decimal place)
