Graphing Systems of Equations

Topic:
Equations
Use the following applet to explore Systems of Equations
Graph the lines below using the slope and y-intercept. What is the solution to the system? Change the y-intercept of the line . How does this change the solution? Changes the y-intercept of both lines. How does this change the solution? Change the slopes of either equation. How does this effect the solution? Hint: If you are having trouble controlling the sliders, you can click on them and use the left and right arrows on your keyboard.
