Question

Need help with this question! Screenshot is attached. Having trouble figuring out the rate of change.

Answer 1

i dont see the attachment

Answer 2

darn its not loading I'll retry

Answer 3

Rate of change is found by taking y2-y1/x2-x1

Answer 4

so you already have your x values 0 and 350, you just need to find your 2 y

Answer 5

also note that y2 is final and y1 is initial starting point.

Answer 6

How do I find the y value with this equation?

Answer 7

if you look on your graph, you can see that when x = 0, y = 50

Answer 8

the next one is kinda tricky, because when x = 350, y looks like its between 25 and 50.

Answer 9

Ya it does, i'm lost on this one

Answer 10

well, i suppose we can say that if half of 25 is 12.5, then we can add 12.5 to 25 which should get us 37.5. That should be between 25 and 50, you see where i'm going?

Answer 11

Yes

Answer 12

Then by using this equation y2-y1/x2-x1.
and the points (0,50) and (350,37.5)

Should look something like this: (37.5-50)/(350-0)

Answer 13

523/14?

Answer 14

-1/28

Answer 15

my bad!

Answer 16

yea and np

Answer 17

Thanks so much!!

Answer 18

yup np
