Linear equation with two variables

The general form of a linear equation in two variables x and y is ax + by + c = 0, where a ≠ 0, b ≠ 0 and a, b, c are constants (real numbers).


For example, Description: 38337.pngis a linear equation with

  • Any equation can be represented graphically.
  • The constant multiplied to a variable is known as its coefficient.
  • The equation ax + by = 0 is called a homogeneous equation as the degree of each term is same.
In the equation ax + by + c = 0, a is the coefficient of x and b is the coefficient of y.
