Answer:
B
Step-by-step explanation:
your only options are b and c but its not 0 so it has to be b
The distance (r) between any two points (a,b) and (c,d) is :—
![r = \sqrt{{(a - c)}^{2} + {(b - d)}^{2} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%7B%7B%28a%20-%20c%29%7D%5E%7B2%7D%20%2B%20%20%7B%28b%20-%20d%29%7D%5E%7B2%7D%20%20%7D%20)
Putting the values,
![\sqrt{ {( - 4 + 8)}^{2} + {( - 3 - 2) }^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B%28%20-%204%20%2B%208%29%7D%5E%7B2%7D%20%2B%20%20%7B%28%20-%203%20-%202%29%20%7D%5E%7B2%7D%20%7D%20)
![r = \sqrt{16 + 25}](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%7B16%20%2B%2025%7D%20)
![r = \sqrt{41}](https://tex.z-dn.net/?f=r%20%3D%20%20%5Csqrt%7B41%7D%20)
The distance between the points is √41
Grou plike terms
4b+9a-2a+5b
4b+5b+9a-2a
9b+7b
the closest one is C, but that has -7b instead of +7b
