Linear Equation
In mathematics, a relationship between two variables that, when plotted on Cartesian axes, produces a straight-line graph; the equation has the general form y = mx + c, where m is the slope of the line represented by the equation and c is the y-intercept, or the value of y where the line crosses the y-axis in the Cartesian coordinate system. Sets of linear equations can be used to describe the behaviour of buildings, bridges, trusses, and other static structures.
