Question

Tasks below.

Answer 1

Do you know what they want when they say "rate of change"?

Answer 2

No, possibly the slope formula? D:

Answer 3

it's very vague..

Answer 4

How fast it changes.

Answer 5

@mew55

Answer 6

???

Answer 7

help? please!

Answer 8

in?

Answer 9

Ya, it is referring to the slope

Answer 10

3 heads are better than 1. and the photo.

Answer 11

sheesh its been a while. i'll do my best

Answer 12

find the slope for the first and last one by using 2 points. Solve part b by putting the equation in slope-intercept form

Answer 13

ok thank you and thank god I'm not taking calculus :( and hmm...I still don't get it.

Answer 14

I thought it was 3 separate things?

Answer 15

slope (change in y/change in x)
(y2-y1)/(x2-x1)

Answer 16

uh huh...so what do I do for the first one? "a" I need an example. I'm very bad at slopes.

Answer 17

letz c
hmmmm.
(2,1)(4,2)
y2-y1/x2-x1
2-1/4-2=1/2, its ur slope
slope-intercept form
for (2,1)
y-y0=m(x-x0)
y-2=1/2(x-1)
y-2=1/2x-1/2
y=1/2x-3/2

Answer 18

I completely don't get it still....um like how do you find a slope for a chart?

Answer 20

mostly its just rise over run. right now i am looking at an example

Answer 21

• you should describe how you found the
answers as well as give the answers themselves.
• Think about how you can find the rate of change given a table, graph, or
equation.

I don't know :(

Answer 22

i am doing the best as i can. i am calculus II now :(

Answer 23

I appreciate it, I'm a straight A student but I always have been bad in math :( and hmm let me look

Answer 24

so how do I change a table to coordinates?

Answer 26

so confusing

Answer 27

I wish I could help! It's been awhile since I've had to find the slope for anything so I'm really rusty. I'm probably learning as much as you right now on how to do it.

Answer 28

can i pick any points from the chart?

Answer 29

Haha well yeah..probably more considering I have literally no idea. I think you have to start from the beginning, like make it into a formula

Answer 30

sorry i lost connection for some reason :/
anywayz, letz pick (2,10) and (4,20)
for slope, we SUBTRACT y2-y1/x2-x1
that will be our slope so
20-10/4-2=10/2=5
then using the slope intercept formula
we can pick any pair of points for our slope so letz try
(2,10)
y-10=5(x-2)
add 10 to both sides
y=5x+8

Answer 31

this is the example, correct?

Answer 32

oops not 8, the y is 0

Answer 33

i took some points from the chart u gave me and yes, thatz an example X3

Answer 34

u understand?

Answer 35

yes, actually...still don't understand how to CHANGE the actual questions.

Answer 36

wut u mean change the actual question?

Answer 37

the actual thing i NEED to do lol

Answer 38

sorry sorry

Answer 39

its 10 over here.
sorry if i wasnt any help. got a cal II quiz tom and really need to improve my grade. class is tough >.<

Answer 40

@surdawi

Answer 41

ok



can you write them as points (x,y)?
