Lesson: Equation of a Straight Line: General Form Mathematics • First Year of Secondary School

Students will be able to

• identify the general form of the equation of a straight line as ,
• find the following properties of a straight line given in general form:
  • the - and intercepts,
  • a missing - or -coordinate for a point that lies on the line,
  • the slope of the line,
• find the equation of a straight line in general form when given
  • the - and intercepts,
  • two arbitrary points that the line passes through,
  • the slope of the line and a point that it passes through,
• convert the equation of a straight line into general form when it is given in
  • slope–intercept form,
  • point–slope form,
  • standard form,
  • two-intercept form.
