The tables each show distance traveled over time of four different vehicles. which table represents a linear relationship? time (hours) 2 6 7 10 14 distance (miles) 140 360 415 580 800 time (hours) 1 5 9 13 17 distance (miles) 55 110 165 210 255 time (hours) 2 4 6 8 10 distance (miles) 24 56 96 144 200 time (hours) 1 2 3 4 5 distance (miles) 3 9 27 81 243

- "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."

answer: the correct answer is -32

step-by-step explanation:

probably .5

i can on others if necessary.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
