Motion pictures typically are filmed and shown at a speed of 24 frames per second, where a frame is a single photographic image in the film. A motion- picture camera that moves the film at 2.4 x 10^5 frames per second is used in high-speed photography. When the film is shown again at 24 frames per second, the filmed object seems to move very slowly. This technique is used to analyze the motion of objects, like bullets, that move too quickly to be observed by the human eye. If a frame of 16-mm film is 0.75 cm in length, how fast does the film move through the high-speed camera when the film is being exposed?

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
