Linear equations and linear inequalities
NettetLinear inequalities look the same as linear equations, except that a region above or below the line (solid or dashed) is shaded to show the area included in the solution. In a system of equations, a pair of linear equations has a single solution at the point where the two lines intersect, unless the lines are parallel, in which case there is no solution. NettetThe phrase "linear equation" takes its origin in this correspondence between lines and equations: a linear equation in two variables is an equation whose solutions form a line. If b ≠ 0, the line is the graph of the function of x that has been defined in the preceding section. If b = 0, the line is a vertical line (that is a line parallel to ...
