Explain how some jobs might use linear or quadratic regression equations that best fit data to make predictions. Describe how the sliders for . m. and . b (y = mx + b) affected the line of best fit as you worked through the Desmos activity. How did the sliders for . a, b, and . c (y = ax. 2 + bx + c) change the quadratic curve?
