To find the approximate value of √19 using a number line, we can locate the whole number closest to the square root of 19, which is 4. Then, we can estimate the decimal portion by dividing the number line segment between 4 and 5 into 10 equal parts and locating the point that corresponds to the square root of 19.
Based on this estimation, the approximate value of √19 on a number line is 4.38 (option D).
