Answer 1

the first 5 problems are similar, so I'll show you one then you do the rest, OK

Answer 2

ok, thanks

Answer 3

so the first one: use the distance formula:
\[d = \sqrt{(y _{1}-y _{2})^{2}+(x _{1}-x _{2})^{2}}\]
\[d = \sqrt{(6--12)^{2}+(-4-8)^{2}} = \sqrt{18^{2}+12^{2}} = \sqrt{468} =21.63units\]
now do the same for 2-5, then we'll discuss the rest
