A linear equation, as the name implies, represents a straight line where the output is an offset

added to a multiple of the input, typically shown as

Y=m*X + b

. The most common use of a

linear equation is with a linear output transducer that measures a phenomenon (for example,

wind speed, power, or acidity) and produces an electrical signal in proportion to that

phenomenon.

A polynomial equation, represents a line that is the sum of coefficients that are multiplied by

powers of the input, typically shown as

Y=a0 + a1*X +a2*X^2 + a3*X^3 + ...

. The order of the

polynomial represents the highest order of power.
