Straight Line Graph

Straight Line Graph

This interactive GeoGebra worksheet allows you to see what the graph of y=mx+c looks like for values of m and c between -5 and 5 by moving the sliders. Have a go and see what happens!

You should note that if m is positive then the line slopes upwards as we go from left to right, if m is negative then the line slopes downwards as we go from left to right and if m is zero then the line is horizontal. The value of m also affects the steepness of the line; the larger the absolute value of a, the steeper the line. Also note that whatever the values of m is, the value of c gives the y-coordinate of the point where the line cuts the y-axis.

If you want to return the sliders to their original positions, then simply click on the icon in the top right hand corner of the worksheet.
