## linear
linear relationship is a relationship between two variables such that, if one is plotted as
a function of the other (see analytical
geometry), the result is a straight line.
If f(x) is a linear function, then f(a+b)
= f(a) + f(b) and c f(x)
= f(cx) must both be true for all values of a, b, c, and x.## Related category• MATHEMATICAL TERMINOLOGY | |||||||
