Finding the Slope on a Geoboard
A rubber band is stretched between two pegs on a geoboard, creating a line that rises from left to right. To find the slope, a right triangle is formed by stretching the rubber band vertically and horizontally from the left peg.
Starting at the left peg and counting the spaces upward to the level of the right peg, the rise is units. Counting the spaces horizontally to the right, the run is units.
Applying the slope definition:
The slope of the line is , which means the line rises units for every units of horizontal distance.
