Mark .75% of way from 0 to 1.
The point that is 3.15 units away from 0 on the positive side of the number line.
Draw a line, from 0, angled at 45 degrees to the number line. Let P be the point at 4.3 units along this line. Drop a perpendicular from P to the number line - to meet it at Q. Then OQ = sqrt(4.3). Repeat on the negative side of the number line.

Irrational numbers can be graphed at a number line, but only as an estimation.
From least to greatest: .....-4 -3 -2 -1 0 1 2 3 4..... etc
It is a number that is approximately equal to 1.4142. Since it is an irrational number, any decimal representation must be an approximation. However, if you have a pair of compasses, it is not that difficult to mark sqrt(2) on the number line.Draw a line at 1 that is vertical to the number line.Put the compass point at 1, radius = distance from 1 to 0 and draw an arc to cut the vertical line at X.Put the compass point at 0, radius = distance from 0 to X and draw an arc. This will cut the number line at sqrt(2).
The same as you would a rational number. Its distance from zero will represent the number, whether it is rational or irrational.
