The inequality "x ≤ 3" can be expressed in interval notation as (-∞, 3]. This means that x can take any value from negative infinity up to and including 3.
To graph the corresponding interval on the number line, you would place a solid dot at 3 on the number line and draw a line to the left that extends infinitely. The solid dot represents the inclusive end point (3), and the line to the left represents all the values less than 3 (i.e., -∞ to 3].
