I have finally updated this with infinite points in a coordinate pair, different graph size options, and quadratic equations! (Please use the exact format shown, including zeros, or it will not read the equation.) --Exponential graphs have not been implemented yet--
This is a 1S1S version accurate graphing calculator for linear equations in the y=mx+b format and quadratic / cubic equations, and is very quick. This calculator heavily uses the "pen" blocks. Please use turbo mode.
