A linear equation in two variables is an equation of the form
where (A, B, ) and (C) are constants.
A graph of a linear equation is a set of all points in the coordinate plane that satisfy the equation.
The graph of a linear equation in two variables is a straight line with slope (A) and y-intercept (C). The slope (A) represents the change in y divided by the change in x, and the y-intercept (C) represents the point where the line crosses the y-axis.
Here are some examples of linear equations in two variables:
The graph of each of these linear equations is a straight line
