Play with the equation: y=mx+b in real life! Change your m by spinning the line 360 degrees or change your b by sliding the line up or down the x and y axes. This fun math tool helps users understand how a straight line can be manipulated by changing the slope and intercepts of a function. Educational Concepts Slope x-intercepts y-intercepts Graphing Components The rotational graphing tool is printed in three parts: a coordinate plane, plug, and line. Simply print each piece, slide the bottom base of the line into the open groove, push the plug into the open groove, and then start graphing! Dimensions 184 mm x 184 mm x 7 mm This is the second version and is slightly different than the one seen in the video.
