The Slope Activity A Gizmo uses the Change in Rise over the Change in Run formula to find the value of the slope of the line. Adjustable sliders make it simple to see the effect that a change in the Rise or Run value has on the overall slope of the line. Easily manipulatable and excellent visual representation of the concept of slope.======

=
Great tool to practice slope identification. Use the sliders or manually drag the points on the graph to change the appearance of the graph, and calculate your slope. For additional support, activate the option to show the rise and run. Another checkbox is then provided to calculate the slope for you, so you can check your work.======

=
Create your graph by using the sliders (which function like choosing ordered pairs) or manually drag the points on the graph, and practice calculating your slope. Additional supports allow for you to see the change in the X and Y values, to compute the slope, and to draw a line through the two points.======

In this manipulative, use the Purple and Green sliders to adjust the value of the Slope (Purple) and the y-intercept (Green), and watch the graph change accordingly.To view the results (and possible solutions) for the graph, click on the Show Tabular Data button.======

=
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.======

OmniGraphSketcher allows users to create simple, yet elegant graphs by simply drawing them, or importing data. Customize the colors and shapes of the lines, label the axes, easily add labels to graph, and export the graph as an image or PDF.======
