I need help figuring out the regression equation and kg.

(10 points) Heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. Height (x) 172 176 168 174 176 166 174 Weight (y) 53 54 50 54 55 47 55 (Note: Compute values to three decimal places of accuracy.) The regression equation is y = Regardless of what answer you actually got, suppose your regression equation were y = -80 + 0.8 x. This line predicts the weight of a supermodel who is 177 cm tall to be kg. Note: You can earn partial credit on this
