Step-by-step explanation:
Use the graphing calculator to plot the line y=ax+b for the given data. On the attached diagram you can see green points that are ordered pairs weight-height and black line is regression line.
As you can see a≈0.1 and b≈50.9.
The equation of regression line is y=0.1x+50.9.
36; Since, as shown by double lines, line BD and DC are the same (18) then the length of BC would be 36.
