Which is the change in scale factor from the old scale to the new scale? 01 to 8
O2 to 8
O 8 to 1
O 8 to 2

1 to 8

Step-by-step explanation:

I took test on edgenuity 2020

1 to 8

Step-by-step explanation:

i took the test

- "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."
