Use your calculator to find the equation of the regression line. 

Write the equation in y=ax+b form.  Do not use any spaces. Round a and  b

 to the nearest tenth.  

Answer 1

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.
