Alex and his friends are driving across the US from New York to Los Angeles at a constant speed without stopping. When they have driven for 10 hours, they are 2400 miles away from Los Angeles. When they have driven for 20 hours, they are 2200 miles away from Los Angeles. a) Find a linear function that models the remaining distance, D, to Los Angeles as a function of the amount of time, t, that Alex and his friends have been driving. D = b) The slope of this function is m = c) The vertical intercept is b %3D d) Explain what the slope and vertical intercept mean in this context.
