Partition the interval [0,2] into 4 subintervals

We will first divide the interval [0,2] into 4 equal length subintervals each of length > (2-0)/4=1/2.

The four subintervals are 

[0,1/2], [1/2,1], [1,3/2], [3/2,2] and the endpoints of these subintervals are 

0, 1/2, 1, 3/2, 2.

correct answer:

b.(19,-2)

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
