An online Graphing Calculator, that can be used to graph up to four equations simultaneously. Standard graphing calculator buttons are available to allow for simple input of an equation, or the equation could be entered manually. A table is provided to find solution sets to a particular equation, or to demonstrate the effects that changes in the independent variable have upon the dependent variable. The graph can also be used to simply plot points on the coordinate plane.======

=
The Slope Slider a good tool to show instantaneous results to changing elements of an equation. 1, Display an equation 2. To solve the equation, begin substituting numbers for X, and see what the resulting y-coordinate was. 3. Adjust slope or other elements to understand the effect they have on the rest of the equation.======
