Students will learn how to draw straight-line graphs in the first quadrant using function machines and tables of values to generate coordinate pairs. Ensure pupils are equipped with a ruler and pencil before they begin drawing their lines.

In section A, students will plot the graphs of y = x + 1, y = x + 3 and y = 2x. Learners will be provided with a function machine, a table of values for x between 0 and 3 and three separate coordinate grids.

Next, in section B, students will plot the graphs of equations such as y = 2x + 1. The scaffolding provided decreases as the section progresses. However, a function machine, table of values and separate coordinate grids are provided for each equation.

All straight lines have positive integer gradients and integer y intercepts.
