1. d^2=(0-0)^2+(1-7)^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.
