y<=7

Explanation:

First, multiply both sides by (-1) and swap the "bigger than/smaller than" symbol.

-5y >= -35 iff 5y <= 35

Now reduce it:

5y <= 35 iff y <= 7

To graph this on a number line, you find 7 on it, and because y<=7, you draw an arrow pointing to the left. This signifies every number equal to or below 7 would work.

Here's an example:
