Quizplus · Accepted Answer

Using the regression feature on a graphing calculator, the linear function that predicts plant growth as a function of temperature is y = 0.21x + 14.57. The coefficient of x represents the slope, which indicates the rate of change in plant growth for every one unit increase in temperature. The y-intercept represents the starting value of plant growth when the temperature is zero. Therefore, the correct choice is D. Using the regression feature on a graphing calculator, the linear function that predicts a plant's growth as a function of the temperature is:
y = 0.21x + 14.57
Therefore, the correct answer is D.
