Solution: x lies strictly greater than -940 and up to -880, so the interval is (-940, -880].

Graph instructions:
- Draw a number line and mark -940 and -880.
- Put an open circle at -940 (because x > -940).
- Put a closed (filled) circle at -880 (because x ≤ -880).
- Shade the segment between them.

Interval notation: (-940, -880]

Simple ASCII sketch (open circle = o, closed = ●, shaded = =====):

... -950 -940 -930 -920 -910 -900 -890 -880 -870 ...
o===== ========== ========== ●

(Interpretation: open circle at -940, filled circle at -880, shading between.)
