The statement "y is at least 2 units from pi" means that the difference between y and pi is greater than or equal to 2. In other words, the value of y must be at least 2 units away from pi on the number line. This can be represented mathematically as:
|y - pi| >= 2
The absolute value is used to ensure that the difference is always positive, regardless of the sign of the expression (y - pi). Thus, y can be either greater than or equal to pi + 2, or less than or equal to pi - 2.
