How can you use the table of values (The spreadsheet bit at the top) to plot a graph from an equation (in blue on the graph). As you change the value of 'm' using the slider, what happens to the equation (in blue)? And what is the effect on the graph? As you change the value of 'c' using the slider, what happens to the equation (in blue)? And what is the effect on the graph?
