2

-2

-1

Answer 8

Considering points (a,b) and (c,d) , \(\LARGE\color{blue}{ \rm{slope}= \frac{b-d}{a-c} }\)

Answer 9

\[\frac{1-(-4)}{-2-3}=\frac{-4-1}{3-(-2)}=-1\]

Answer 10

Thank you!

Answer 11

in your case, you have

(3,-4) and (-2,1)

So, \(\LARGE\color{blue}{ \rm{slope}= \frac{(-4)-(1)}{(3)-(-2)}=\frac{-5}{5}=-1 }\)

Answer 12

Satelline is fast.

Thank you both! I have 4 more, if you don't mind?

Answer 14

Alex is saving money because she would like to purchase the new video gaming system that everyone has been talking about. After two weeks of saving, she had $47. After 24 weeks of saving, she had $430. Approximately how many dollars per week did Alex save on average between weeks 2 and 24?

$15.96 per week

$17.41 per week

$17.91 per week

$19.88 per week

Answer 15

24 weeks after the 2 weeks, or 24 weeks and 2 weeks are within them ?

Answer 16

saying is it 6 or 24 altogether.

Answer 17

I mean 26 nor 24

Answer 18

I think it's excluding the 1st 2 weeks and it just means how much she saved between weeks 2-24

Answer 19

*or

Answer 20

weeks 1-2 she saves 47 AND
weeks 1-24 (all weeks) she saves 430

Answer 21

the average between 2-24 weeks, I would think that the weeks it is asking about is 3,4,5,...23,24.

430 - 47 = 383 (is how much she saves starting after the week 2)

383 ÷ 22 = average starting from the 3rd week, and till the end of 24th

Answer 22

383 ÷ 22 = 17.4090909090909090.... ≈ 17.41

Answer 23

Thank you!
