Explanation:
The slope means : A.
the increase in the number of pounds a boy gains each year
Explanation:
Given the equation for line of best fit as : y=1.73x +80.13
At the age of 5 the weight will be;
x=5, y= 1.73*5+80.13 =88.75 pounds
At the age of 6, the weight will be;
x=6, y=1.73*6+80.13 = 90.15
Difference in weight after one year increase of age will be;
90.15-88.75=1.73
This means after a year, a boy gains 1.73 pounds

Planet A is an outer planet, and Planet B is an inner planet, then Planet A will spin (rotate on its axis) faster than Planet B.
Using our Solar System as a model, we may determine the following:
The inner planets, which include our Earth, Mercury, Venus, and Mars, revolve more slowly than the outer planets (such as Jupiter, Saturn, Uranus and Neptune). The reason for this is because the nearest planets are held firmly in place as they revolve around the Sun due to the massive gravitational field of the star.
However, for the same reason (because of their proximity to the Sun's gravitational field), inner planets complete one circle around the Sun faster than outer planets.
As a result, Planet A will spin (rotation on its axis) faster than Planet B if Planet A is an outer planet and Planet B is an inner planet.
