Answer:

-2

Step-by-step explanation:

We can find the slope of a line by using two points

(-2,1) and (2,-7)

The slope is given by

m = (y2-y1)/(x2-x1)

= (-7-1)/(2- -2)

= (-8)/(2+2)

= -8/4

=-2

A circle has a radius of 9 ft. Find the length of s of the arc intercepted by a central angle of 97 degrees. Do not round any in

Sedaia [141]

$\bf \textit{arc's length}\\\\
s=\cfrac{\theta \pi r}{180}\quad 
\begin{cases}
r=radius\\
\theta =angle\ in\\
\qquad degrees\\
------\\
r=9\\
\theta = 97
\end{cases}\implies s=\cfrac{97\cdot \pi \cdot 9}{180}$
