An equation in which the unknown has highest power 1, so its graph would be a straight line.
Revise: Linear EquationsOtherwise, a linear equation in one unknown normally has one solution.
An equation in which the variables have highest power 1, such as .
For a linear–quadratic pair, substitute from the linear equation into the quadratic one. Keep every root of the resulting quadratic and find its corresponding second coordinate.
