Slope Triangle Exploration

Description: The applet below is an exploration of slope in the function f(x) = mx + b. Experiment by changing the values of the different variables in the equation (m and b) and changing Triangle EDC (the length of the sides and the placement on the line). What You Can Change:
  • The values for b (slider b)
  • The values for m (slider m)
  • The length of the side c of Triangle EDC (slider )
  • The placement of Triangle EDC on the line
