Answer: (3,8) and (-2, 10)
Step-by-step explanation:
the slope of the line passing
B, because you would just assume the line continues forever on both sides.
Answer : B
the distance between the points (4,3) and (2,-1)
We apply distance formula

(x1,y1) is (4,3)
(x2,y2) is (2,1)


d^2 = 4+16 = 20
Take square root on both sides
So 
the distance between the points (4,3) and (2,-1) is 2sqrt(5)
Answer: 11+5=16
