Answer:
Dependent variable = Height
Independent variable = foot length from toe to heal
Explanation:
In a scatter plot, line of the best fit is represented by the line in the form of
y = mx + b
where y is the dependent variable (plotted on y- axis)
and x is the independent variable (plotted on x-axis)
In the given question 'height' has been plotted on y-axis therefore, Height will be dependent variable.
And foot length from toe to heal has been plotted on x-axis therefore, foot length from toe to heal will be independent variable.
