Each runner is carrying an 8 ounce bottle of water, a 2.1b ounce energy bar, and a 3 ounce energy drink. Write an expression in the simplest form that represents the weight carried by y runners.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
