A linear equation is an algebraic equation in which each term is either a constant
or the product ... A common **form** of a linear equation in the two variables x and y
is. y = m x ... the slope or gradient of that line, and the constant term b determines
the point at which the line crosses the y-axis, otherwise known as the **y**-**intercept**.
