Answer:
2.5mm per week.
Explanation:
To determine how fast Rip van Winkle's beard grew, we calculate the slope of the line.
To do this, pick two points on the line: (0,10) and (10,35)
[tex]\begin{gathered} \text{Slope},m=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =\frac{35-10}{10-0} \\ =\frac{25}{10} \\ =2.5\text{ mm per week} \end{gathered}[/tex]
Rip van Winkle beards grew at a rate of 2.5mm per week.
