A bus leaves at 10AM to takes students on a field trip to a historic site. At 10:25 AM, the bus is 100 miles from the site. At 11:15 AM, the bus is 65 miles from the site. The bus travels at a constant speed of 60mph. Write an equation in point-slope form that relates the distance (in miles) from the site and the time (in minutes) after 10 AM.
y - 100 = -0.7(x - 25) or y - 65 = -0.7(x - 75)
