Aregression 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=-0.662 b=30.418 r2=0.703921 r=-0.839

Which point is on the line y=-2+3? (-2,-1) (3,3) (3,-3) (-3,-9)

What is the value of r of the geometric series?
