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.
