Modeling a Line with Slope on a Geoboard
To model a line with a given slope on a geoboard, use the slope formula to determine how many units to move vertically and horizontally between pegs.
For a slope of , set up the formula:
This tells us the rise is and the run is . To build the line on a geoboard:
- Start at a peg in the lower-left area of the board.
- Stretch the rubber band up unit and then right units to reach a second peg.
The hypotenuse of the resulting right triangle represents a line whose slope is . This process works in reverse compared to finding the slope of an existing line — here the slope is known, and the rise and run are used to place the rubber band.
