Linear Equation

This linear equation applet can show three different formulas for the same graph, on the left we have the slope- intercept form, the middle one is the standard form and the one on the right is the point- slope form. The three sliders a, b, and c are the coefficients, and the range for all the sliders is from -5 to 5. Coefficients a and b control the slope of the line.While c and b control the y-intercept point.
