To find the approximate value of √19 using a number line, we can plot the numbers and estimate where √19 falls between two whole numbers.
On a number line, locate the numbers 4 and 5 (because 4² = 16 and 5² = 25).
0 1 2 3 4 5 6
----|----|----|----|----|----|----|----|----|----|----|----|----|----|----|--
-6 -5 -4 -3 -2 -1 0 1 2 3 4
Since 19 is greater than 16 (4²) but less than 25 (5²), we can estimate that √19 lies closer to 4 than it does to 5.
Therefore, the approximate value of √19 on the number line is closer to 4.
