In this lesson we will learn how to plot any straight-line graph from a table of values. You will learn tips on accurately plotting your points and how to avoid common mistakes often made by students when drawing graphs.

The questions covered in this lesson are i) plot the graph of $y$ = 2$x$ +1 ii) plot the graph of y = -3$x$ + 5
