I’m not sure about number 1 but the answer for number 2 is
-4 1/2, -4.2, -4, ,0, 4
The answer should be A. 4.5
Because line x is just over half of the length of the line that is 8ft
It is proportional because the number are even and can be divided by the same number
if your asking for the equation, it's t + 7 < 3
