Points that do not fall on a straight line suggest contamination, and this invalidates the results.However, by this same principle, points falling relatively close to a best fit line should provide an accurate date for the age of the rock being dated (Stasser 1992).While isochron dates have been used by both old-Earth and young-Earth proponents to promote their respective viewpoints, attacks on isochron dating have also been made by young-Earth creationists, such as William Overn.
However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid.The plot of the ratios of the number of atoms of the parent isotope to the number of atoms in the non-daughter isotope compared to the number of atoms of the daughter isotope to the non-daughter isotope should result in a straight line that intersects the vertical y-axis (which is the ratio of daughter to non-daughter isotopes).This point of intersection gives the initial ratio of daughter to non-daughter isotopes, which would also be the ratio in a mineral that crystallized without any parent isotope present.Thus, the daughter product and any other isotopes of the same element will be incorporated into the minerals of a rock with the same ratio.This initial ratio allows the non-daughter product isotope to be representative of the initial amount of the daughter product (Stassen 1998).

In most cases, the slope of the line generated by the isochron method gives an age for a rock sample of millions, or even billions of years.
