How did we find the points to graph this?
Answer provided by our tutors
For linear equations, a Line Wizard titled 'Evaluate a linear equation' is tailored for tabulated point pairs. For non-linear equations, simply replace 'x' with a numeric value and solve for 'y' as often as you need specific point pairs.
It is clear from the graph the x=0 identifies the (x,y) coordinate (0,0).
