The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours: based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed? a. the dependent variable is distance, the equation is y = 25x, and the dragonfly will travel 600 miles. b. the dependent variable is distance, the equation is x = 25y, and the dragonfly will travel 720 miles. c. the dependent variable is time, the equation is y = 25x, and the dragonfly will travel 600 miles. d. the dependent variable is time, the equation is x = 25y, and the dragonfly will travel 720 miles.
