 The general form of a linear, equation in two variables is:
  •  ax + by + c = 0, where a, b, c are real numbers and a, b ≠ 0

  • ax + b = 0 where a, b are real numbers and a ≠ b

  •  ax2 + bx + c = 0, where a, b, c are real numbers and a, b ≠ 0
  • none of these 

Answer

A.

 ax + by + c = 0, where a, b, c are real numbers and a, b ≠ 0
