What are you supposed to do with 1) and 2)

3) The equation for the slope is m= (rise)/(run) = (change in y)/(change in x)

The 'change in y' is -1800 ft (it's negative because he decended)

The 'change in x' is 3.25 miles = 3.25*(5280ft) = 17160ft

m = -1800/17160 = -0.104895 ... when rounded to the nearest hundredth = -0.10
