The variable that you would have to plot on the y axis (height) is the dependent variable while the variable that is on the x axis (arm span) is the independent or the explanatory variable.
<h3>How to get the slope of the line</h3>
The slope was gotten through the use of the points (37,39) and (19,25)
This gave the slope of 7/9. This tells us that height of the person got to be raised by 7/9 inches when arm span increases by 1 inch.
From the given model, a person that has the arm span of 66 would have the height of
12 + 7/9 * 66
= 63.3 inches
A person who is 74 inches height the arm span of = 62*9/7
= 79. 71 inches.
