Answer 2

Answer:

B.  (6, -1) and (6, 3)

Step-by-step explanation:

A. The distance is = $\sqrt{(8-1)^{2} +(4-4)^{2} }$ = 7 unit.

B. The distance is = $\sqrt{(6-6)^{2} +(3-(-1))^{2} } = \sqrt{(3+1)^{2} }$ = 4 unit.

C. The distance is = $\sqrt{(7-(-3))^{2} +(0-0)^{2} }$ = $\sqrt{(7+3)^{2} }$ = 10 unit.

D. The distance is = $\sqrt{(6-(-2))^{2} +(10-2)^{2} }$ = $\sqrt{(6+2)^{2}+8^{2} }$ = $\sqrt{8^{2}+8^{2} }$ = $8\sqrt{2}$ unit.
