Question 3(Multiple Choice Worth 3 points) (07.06) Which of the following graphs shows all the possible values for a number that is more than 8? Number line with closed circle on 8 and shading to the left. Number line with closed circle on 8 and shading to the right. Number line with open circle on 8 and shading to the left. Number line with open circle on 8 and shading to the right.

1/2*qr*rs

step-by-step explanation:

- "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."
