Answer 1

The ray will move the right

Answer 2

The ray will move to the left and it will use an open circle.

Explanation:

The ray will move to the left because x < 4.5 is the same thing as -∞<x<4.5,

It will be a open circle because x is not less than or equal to 4.5, it is this: x is less than 4.5.
