Jenn:   12/30 incorrect  18/30 correct

Mara.    8/24 incorrect   16/24 correct

Step-by-step explanation:

Could you ask the question This isn’t a questions it more like a statement so I tried to do my best and I just made them into fractions

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

- "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."
