Someone please help me answer this!!

The answer to your question is below

Step-by-step explanation:

Both graphs have the same shape, and both functions have the same y-intersection (0, 1)

f(x) = 2 is over the x-axis, while in the function

g(x) = 4(2) - 7 , +1, means that the graph is displaced 1 unit to the left, and

                             - 7 means that the graph is displaced 7 units down, and

                              4 means that the graph is four times bigger than the

                               function f(x)

- "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."
