A square bracket means that the interval includes that endpoint. Since in your problem both brackets are square, both endpoints are included. This interval goes from -4 to 10 and includes the endpoints -- on a number line, you fill in those endpoints. Alternatively, instead of filling in the endpoints, you can draw a bracket at -4 and another bracket at 10. If the interval had included parentheses, you would not have filled in the circles (or if you used brackets/parens, you would have put a paren on the number line).
