First, substitute.

-9 = 2(-2) - 5
-9 = -4 -5
-9 = -9
Yes, the point (-2, -9) satisfies the equation

y = 2x - 5 \\  - 9 = 2( - 2) - 5 \\  - 9 =  - 4 - 5 \\  - 9 =  - 9
Since, both sides of the equation equal each other, that means it does satisfy this specific equation.

The inequality would start out looking like this:
-30\ \textless \  \frac{5}{9} (F-32)\ \textless \ 130
Now it's just a matter of solving the inequalities simultaneously. Get rid of the fraction by multiplying everything by 9:
-270\ \textless \ 5(F-32)\ \textless \ 1170
Then distribute the 5 into the parenthesis:
-270\ \textless \ 5F-160\ \textless \ 1170
Now add 160 everywhere:
-110\ \textless \ 5F\ \textless \ 1330
and finally divide everything by 5:
-22<F<266
