Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, b)</em>
The formula of a slope:

From the table we have an y-intercept (0, 9) → b = 9.
Take other point from the table (-6, -1).
Calculate the slope:

Finally:

The arc length is given by
.. s = rθ . . . . . . θ is the central angle in radians
.. = (8 in)*(35/180*π)
.. ≈ 4.9 in
