Question

Please help me ^.^

Answer 1

we can use the slope formula to calculate the rate of change

if x1 = 1 and x2 = 3
and y1 = 20 and y2 = 10

then (y2-y1)/(x2-x1) = slope = ?

Answer 2

What am I suppose to do?

Answer 3

hmmmm

Answer 4

if x1 = 1 and x2 = 3
and y1 = 20 and y2 = 10

replace "x1" with 1, x2 with 3, etc.

and calculate (y2-y1)/(x2-x1)

Answer 5

Is it D? ^.^

Answer 6

please follow my instructions

Answer 7

is he right tho?
he might have just worked it by himself and needs you to tell him if he is right or not

Answer 8

so its D right?

Answer 9

no

Answer 10

y/x?

Answer 11

how?

Answer 12

look at the x intervals

Answer 13

ohhhhhh okay now i see so its B? i might be wrong

Answer 14

@UsArmy3947 can you take a look at my diagram and calculate the slope please? I have drawn arrows to the numbers you are supposed to fill in

Answer 15

I thought D.

Answer 16

thats what i thought

Answer 17

if you look at the diagram

slope = (10-20)/(3-1) = ?

Answer 18

-10/2?

Answer 19

yes, and that simplifies to...?

Answer 20

-5

Answer 21

good! so your rate of change is -5, which eliminates everything except C

Answer 22

:O thanks....

Answer 23

I got it wrong :( wasn't C

Answer 24

wait what

Answer 25

wait... oh I changed the answer choice of the wrong question
