Answer
a) see plot on the number line
b) Rhode Island, Georgia, Louisiana, Florida, Hawaii
Work Step by Step
a) The Record Low ($^\circ F$) information is plotted on the number line below.
b) On the number line, a number on the right is greater than the numbers on the left. Hence, the order (from coldest to warmest) of the given temperatures ($^\circ F$),
$-2,$ $\text{ }$ $-17, $ $\text{ }$ $12,$ $\text{ }$ $-16,$ $\text{ and }$ $-25,$ is
\begin{array}{l}\require{cancel}
-25^\circ F
\text{ (Rhode Island),}
-17^\circ F
\text{ (Georgia),}
-16^\circ F
\text{ (Louisiana),}
-2^\circ F
\text{ (Florida), }
12^\circ F
\text{ (Hawaii)}
.\end{array}
