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.
Answer:
The length of the line GA would be 13
Step-by-step explanation:
G is the circumcenter (where the perpendicular bisectors of a triangle intercept) of the triangle. The line GA is one of those perpendicular bisectors. The two dashes on the sides of the triangles show that they are all equivalent on that side. The two squares show that they art right triangles. This means the lines GB and GA are equivalent. So if GB=13, then GA=13.
You have to subtract 13-7 then see what you have to multiply by three to get six
