Answer 3

this is just a matter of subbing in your answer choices into the equation to see if it is true.
I will do the first one for you...

y = 8x
using (0,8)...x = 0 and y = 8
now we sub
8 = 8(0)
8 = 0 (this is not a solution because it is false

you wanna ry the next answer choice ?

Answer 4

* try

Answer 5

Let me try the next one. Kind of see if I understand :)

Answer 6

take your time...I am not leaving

Answer 7

8x, -1 = x and 8 = y


8 = 8(-1)

8 = -8, it isnt true. So B isnt an option

Answer 8

Am I correct? :)

Answer 9

you definitely are correct...way to go.
wanna try the next one ?

Answer 10

Sure :)

Answer 11

x = 1.5, y = 10

8 = 1.5(10)

8 = 15 is not correct, That leaves D. But I want to make sure it is D.

Answer 12

x = 2, y = 16

8 = 2(16)

2(16) = 32.........Not the answer....Now I am confused o.O

Answer 13

you got your numbers (x and y) mixed up
y = 8x
(1.5,10)

10 = 8(1.5)
10 = 12 (it is still false, but be careful of where you put your x and y numbers

Answer 14

Oooooooh. Oops. Sorry! Lol

Answer 15

y = 8x.....(2,16)...x = 2 and y = 16
16 = 8(2)
16 = 16 (correct....so it is D)

Answer 16

any questions ?

Answer 17

Not really. Still kinda confused tho. I dunno why, because you stated how to do you clearly.

Answer 18

just remember, in all points, the x is the first number and the y is the second (x,y)

Answer 19

Alright. Thank you! :)

Answer 20

anytime :)
