Lesson Plan: Equation of a Straight Line: General Form Mathematics • First Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find and write the equation of a straight line in general form.
Objectives
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.
Prerequisites
Students should already be familiar with
- equations of a straight line (although not necessarily the name and methods related to each form),
- finding the slope of a line from coordinates.
Exclusions
Students will not cover
- equations of curved lines,
- function notation.
