Q1. Find the length of the following segment created by these pairs of endpoints: (0, 1), (0, 7)
Answer : 0
Q2. Find the length of the following segment created by these pairs of endpoints: (9, 6), (12, 6)
Answer : 3
Q3. Find the length of the following segment created by these pairs of endpoints: (1, 2), (7, 2)
Answer : 2

1. d^2=(00)^2+(17)^2 solve for d, it is not zero.
2. same formula, answer is correct.
3. The answer is not two.
Now on these, the answers are obvious: THINK. On the first, it is a line along the x axis going from 1 to 7, length..
On the second, it is a vertical line at x=6, going from y=9 to 12. Yep, that is a distance of 3
On the third, it is a horizontal line along y=2 from x=1 to seven, which is not a length of 2.
