Answering that would be a snap if I could have a peek at the line, but until then, it's totally impossible.
Plane.
Not normally because an irrational number can't be expressed as a fraction which can be represented on the number line.
These number can also be represented on real line.
fractions are represented in form of decimals
It is the real number whose length represents the distance from the zero on the line to the point on the line.
A real number can be represented by a point on the number line.
A triangle, with one of the complex numbers represented by a line from the origin to the number, and then move from that point up and over the amount of the next complex number. Then draw a line segment from the origin to the final point.

It is 0.58, of course. The number line is not simply for integers!
The point that is 3.15 units away from 0 on the positive side of the number line.
point D
The nearest whole number is 1, so that could be the best number.
Irrational numbers can be represented on a number line. For example, to graph the square root of two, draw a line of 1 unit (1 unit = the distance between the points of two whole numbers) from -1 which is perpendicular to the number line. Then, using a compass, place the pointy end on 0, the pencil tip on the end of the drawn line that is not touching the number line and drawing an arc so that it hits the number line on the positive side. Draw a point at where the arc meets the number line. That point is the square root of 2. This works because of Pythagoras theorem (a2+b2=c2, 12+12=22).
