Need in number 2. i start school tomorrow and it’s due tomorrow

See below.

Step-by-step explanation:

Pardon my confusion, but is that negative 4 and 1/2 or negative 4 times 1/2?

If it is negative 4 and 1/2, then you could just mark -4 and -5 on the number line and put the solid dot half way between them. Essentially you'd be marking -4.5 on the number line. If you wanted a more nuanced answer to that:

-4 and 1/2 = -(4 + 1/2) = -8/2 -1/2 = -9/2

If it is negative 4 times 1/2, then:

-4×1/2 = -4/2 = -2

So you would mark the solid dot wherever you place -2 on that number line. And it's "less than or equal to" for both so the arrow goes left.
