Investigating Straight Line Graphs WORKSHEET

Suitable for Year groups: Year 8, Year 9
GCSE Tier: Foundation/Higher
Targeting grades: 4-5
Prerequisite knowledge: Coordinates on four quadrants.
Learning Objective: Recognise, sketch and produce graphs of linear functions

Investigating Straight Line Graphs WORKSHEET DESCRIPTION

This worksheet encourages students to utilise graphing software such as desmos and autograph in order to investigate the y-intercepts and gradients of linear functions. Broken down into three sections, learners will take a look at gradients, and y intercepts separately before considering equations in form y = mx + c.

Students will make use of ‘sliders’ throughout their investigation as well as using the software to generate tables of values.

By the end of their investigation, students will recognise the effect m and c have on y = mx + c, including fractional and negative values, be able to complete a table of values using equations and state the equations of lines from a table of values.

All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions

This resource is designed for Year 8 and Year 9 students who are developing their understanding of linear functions. It's particularly effective for learners who have mastered plotting coordinates across all four quadrants and are ready to explore how equations relate to their graphical representations. The interactive nature of the investigation makes it engaging for students at this key stage.
