The line y = m x + b with a Point

Move the m and b sliders one at a time, and then together to discover how each transforms the line.
Click the point and slide it along the line to find any coordinate point on any line.
Use the refresh button at the top right of the applet to reset the applet to its original state.

If you double click on the grid, the GeoGebra program will open with this applet and you will have more controls.

REMEMBER:

m is the slope is

the rate of change of y with respect to x.

the constant of variation k in the equation y = k x

b is the initial condition, or the y–intercept.

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)
