Answer: B coordinate (-24, 18.8)
Explanation:
If point B lies on the segment AC at the midpoint, find the slope of the linear line.
distance between 2 and -30 is 32 on the x and 24 on the y
24 dived by -30 gives slope = -.8
AB should be 1/8 of AC therefore, 1/8 times 32, and add it to the -30 giving you the x value of B.
32 times 1/8 is 4
4 plus -30 is -24 giving the x value for b
using the slope of -.8 multiplied by 4 to get -3.2
22 plus -3.2 gives you 18.8
B's coordinates of (-24, 18.8)
