Important Formulas: Linear Equations in Two Variables | Mathematics for EmSAT Achieve PDF Download

An equation of the form ax + by + c = 0, where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in two variables.

Important Points 

  • A linear equation in two variable has infinite solutions
  • The graph of every linear equation in two variable is a straight line
  • x = 0 is the equation of the y-axis and y = 0 is the equation of the x-axis
  • The graph x = a is a line parallel to y -axis. 
  • The graph y = b is a line parallel to x -axis
  • An equation of the type y = mx represents a line passing through the origin. 
  • Every point on the graph of a linear equation in two variables is a solution of the linear equation. Moreover, every solution of the linear equation is a point on the graph
