Determining an equation and type of graph jeff hiked for 2 hours and traveled 5 miles. if he continues at the same pace, which equation will show the relationship between the time, t, in hours he hikes to distance, d, in miles? will the graph be continuous or discrete? d = 0.4t, discrete d = 0.4t, continuous d = 2.5t, discrete d = 2.5t, continuous
