13. 12 3/8
14. 9 2/3
15. 3 4/10
16. 3
Use the slope formula:
(y2 - y1)/(x2 - x1)
(x1, y1) = (-5, 1)
(x2, y2) = (-4, -4)
In my calculation is divide it 0.00018333333
and if multiply it well be 6600
The answer is D because all the rest of the statments are untrue. d is also right because 4 people walked 3-5 miles and 3 people walked 6-8 miles and as you know, 3+4=7
