Using R to draw the equation of a straight line graph - Part 2

This lesson follows on from ‘Using R to draw the equation of a straight line graph - Part 1’ and demonstrates how to use R to plot straight line graphs (y=mx+c) with different intercepts and negative gradients followed by questions on the observed differences.

There are then plenty of activities to practice using the code.

The maths is KS3 level.

This lesson assumes some knowledge of working in an R Markdown file which can be gained by working through the ‘My First Introductory R Lesson using R Markdown’ and ‘My Second Introductory R Lesson using R Markdown’ both available on TES.

No previous knowledge of R coding language is needed.

The contents of the word file needs to be copied into an R Markdown file before use.

This lesson assumes that you have installed RStudio or have access to RStudioCloud.
