The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
A graph titled Motion of a Dragonfly shows Time in hours on the x axis and Distance in miles on the y axis. The scale on the x axis shows number from 0 to 10 at increments of 2 and on the y axis the numbers are shown from 0 to 250 at increments of 50. A straight line joins the ordered pairs 0, 0 and 2, 50 and 4, 100 and 6, 150
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 t

Best ResponseYou've already chosen the best response.0The dependent variable is distance, the equation is y = 25x, and the dragonfly will travel 600 miles. The dependent variable is distance, the equation is x = 25y, and the dragonfly will travel 720 miles. The dependent variable is time, the equation is y = 25x, and the dragonfly will travel 600 miles. The dependent variable is time, the equation is x = 25y, and the dragonfly will travel 720 miles.

Best ResponseYou've already chosen the best response.2yes the 'distance' the dragonfly can fly is the dependent variable, [this distance depends on how how much time the dragon fly has]

Best ResponseYou've already chosen the best response.2the slope intercept form of a straight line through the origin, is y = mx + b when the slope of the line is m and the yintercept is b.

Best ResponseYou've already chosen the best response.2we see that the line passes through the origin, so we know that b=0. but what is the slope m?

UnkleRhaukus

Best ResponseYou've already chosen the best response.2if we find the slope between (0,0) and (2,50) m = (500)/(20) = 50/2 = 25 so yes the slope m is 25

Best ResponseYou've already chosen the best response.2you have y(x) = 25x or equivalently distance(time[hours])[miles] = 25[miles/hours] * t[hours]

Best ResponseYou've already chosen the best response.2\[25 [\text{mi}/\text{hr}] \times 24[\text{hr}] =(25\times24)\frac{[\text{mi}][\text{hr}]}{[\text{hr}]} \\ =(25\times24)\frac{[\text{mi}]\cancel{[\text{hr}]}}{\cancel{[\text{hr}]}} \]

Best ResponseYou've already chosen the best response.1bunch of physics problems have numbers and units. so we need to keep the units while we're computing... otherwise the grader will be like 600 what ? 600 miles
