Answer 3

slope formula

\[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

Answer 4

i think I'm going to go with either C OR D .

Answer 5

why?

Answer 6

well because height adds up to 7

Answer 7

if you pick on choice C

does plugging in x = 2 give you y = 8?

Answer 8

yes i think so , lol

Answer 9

y = 7x+1
y = 7*2+1 ... replace x with 2
y = ???

Answer 10

7

Answer 11

huh?

Answer 12

wrong thing . i mean

Answer 13

Answer 14

y=7 .. right ?

Answer 15

what is 7*2+1 equal to

Answer 16

=15

Answer 17

which is not 8 like we want

Answer 18

for y = 7x+1, if x = 2 then y = 15 (not y = 8). So the equation for choice C doesn't work

Answer 19

okay , next is D

Answer 20

that is +8

Answer 21

does plugging x = 2 into that give you y = 8?

Answer 22

yes.

Answer 23

Answer 25

what does it give you?

Answer 26

10?.,

Answer 27

Answer 46

plug in x = 2 and see what happens

Answer 47

you can think of 7/2 as 3.5

Answer 48

y = 3.5x + 8

y = 3.5*2 + 8 ... replace x with 2

y = ???

Answer 49

11.5 /?

Answer 50

3.5*2 + 8 = ???

Answer 51

15

Answer 52

so B is out

Answer 53

i know i know !

Answer 54

A IS the correct answer!

Answer 55

let's check choice A

y = 3.5x + 1

y = 3.5*2 + 1 ... replace x with 2

y = ???

Answer 56

8

Answer 57

yep I suggest you check the other x values in the table

Answer 58

okay I will thank you so much :P
