Run this generator on turbo mode by holding shift and clicking the green flag. Press the "A" key to generate a quadratic graph, and press the space key to generate a linear graph. Each tick mark counts for 10 units. Click A or space to reset the graph too.
Set A and B to a decimal less than 1 if you want to see the parabola open up more, anything higher than 2 will make it really tight and hard to see.
