To approximate the value of √19 using a number line, we can start by finding two perfect square numbers on the number line that √19 falls between. The perfect square numbers closest to 19 are 16 (4²) and 25 (5²).
Since 19 is closer to 16, we know that √19 will be closer to 4.
The approximated value of √19 is closer to 4.13, which falls between 4 and 5 on the number line.
Therefore, the answer is B. 4.13.
