The wind-chill index I is the perceived temperature when the actual temperature is T and the wind speed is v so we can write I = (T, v). The following table of values is an excerpt from a table compiled by the National Atmospheric and Oceanic Administration. Use the table to find a linear approximation L(T, v) to the wind chill index function when T is near 16°C and v is near 30 kmh.
