Lesson Plan: Slopes and Intercepts of Linear Functions Mathematics • 8th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify slopes and intercepts of linear functions algebraically.

Objectives

Students will be able to

  • calculate the gradient of a line passing through two points using the formula 𝑚=(𝑦𝑦)(𝑥𝑥),
  • find a point on a line given another point on the line and the gradient,
  • convert between the slope–intercept form of a line (𝑦=𝑚𝑥+𝑐) and the general form (𝑎𝑥+𝑏𝑦+𝑐=0),
  • use the equation of a line in the form 𝑦=𝑚𝑥+𝑐 or 𝑎𝑥+𝑏𝑦+𝑐=0 to identify the gradient and intercepts of the line.

Prerequisites

Students should already be familiar with

  • rearranging equations,
  • lines and the intersection points of lines.

Exclusions

Students will not cover

  • the equation of a line in the form 𝑦𝑦=𝑚(𝑥𝑥),
  • finding the equation of a line passing through two points,
  • parallel and perpendicular lines.
