Graphing a function rule to see questions go to pdf attachment below.
i need to catch up on alg 1a, and it would be great if someone could check my answers.
here are the answers i got
1.d
2.b
3.b
4.a
5.c
do not answer if you do not know the answer or i will do the same to all of yours and haunt you lol. i am giving a lot of points because i want to get through this quickly. if you know most the answers but are not sure on one tell me, and you for all of your ! if you want brainliest you must answer all of the questions.

- "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."

5+2x=a
