Pixel Power Part 2

This video will guide students through the process of determining the equation of a line.

Learning Objectives

  • Analysing a line on a Cartesian plane to determine it
  • Plot lines on a Cartesian Plane.

Guiding Ideas

  1. Plot points in a straight line going through the origin
  2. Use the gradient formula m = rise/run
  3. Allow students to see the pattern y = mx
  4. What happens if the line does not go through the origin?
  5. Show how the y intercept works.
  6. Practice making equations form lines and plotting equations.

Student Activities

1.Watch the Video Pixel Power! Part 2. It will take the students through the concept of plotting a line to the use of the equation format y = mx + c

2. Students make their own cartesian plane and make a series of lines in their own choice of blocks. Using signs, place the equation next to a block on the ground representing that line. For example, make a diamond block line. Place a diamond block on the ground with a sign on it showing the equation.

3. Give students equations and challenge them to plot them!

Performance Expectations

  • Be able to plot lines on a Cartesian Plane
  • Be able to calculate the gradient of all lines
  • Be able to determine the y intercept of a line.
  • Be able to create the line equation using the gradient and y intercept.
  • Be able to plot a line form it's equation.
