Question

the points are now connected with a line, m. find the slope of line m, or the change in the length of the scarf after one day. slope = a box with 9 inside length of the scarf (cm) number of days

Explanation:

Step1: Identify two points

Use points $(x_1,y_1)=(0,0)$ and $(x_2,y_2)=(2,9)$

Step2: Apply slope formula

Slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$
$\text{Slope}=\frac{9-0}{2-0}=\frac{9}{2}=4.5$

Answer:

4.5
