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 = \square

Explanation:

Step1: Identify two points on line m

We can use the points $(4, 14)$ and $(6, 21)$ (or any two distinct points on the line).

Step2: Apply slope formula

Slope is calculated as $\frac{y_2 - y_1}{x_2 - x_1}$. Substitute the points:
$\frac{21 - 14}{6 - 4} = \frac{7}{2} = 3.5$

Answer:

3.5
