Answer:
Distance formula: (x1,y1), (x2,y2)
d = √[(x2-x1)2+(y2-y1)2]
d = √[(5-2)2+(4-1)2]
d = √(32+32)
d = √18
d = 3√2
double this distance: The length is 6√2
it's of first one
Step-by-step explanation:
its of second one
The formula for midpoint = (x1 + x2)/2, (y1 + y2)/2. Substituting in the two x coordinates and two y coordinates from the endpoints, we get (–1 + 3)/2
