An equation is said to be linear equation in two variables if it is written in the form of ax by c0 where a b c are real numbers and the coefficients of x and y ie a and b respectively are not equal to zero for example 10x 4y 3 and x 5y 2 are linear equations in two variables. Linear equations in two variables in this chapter well use the geometry of lines to help us solve equations linear equations in two variables if a bandr are real numbers and if a and b are not both equal to 0 then ax by r is called a linear equation in two variables the two variables are the x and the y the numbers a and b are called the coecients of the equation ax by r . A linear equation in two variables such as 2x y 7 has an infinite number of solutions its graph is a line remember every point on the line is a solution to the equation and every solution to the equation is a point on the line. A linear system of two equations with two variables is any system that can be written in the form ax by p cx dy q a x b y p c x d y q where any of the constants can be zero with the exception that each equation must have at least one variable in it
