Answer 1

PLEASE HELP!

Answer 2

(24, 12)
(12, 6)
\(\dfrac{6 - 12}{12 - 24} = \dfrac{1}{2}\)

Answer 3

sorry i dont understand.. this is confusing to me

Answer 4

so it would be C
because \(\dfrac{24}{2} = 12 \\ \dfrac{12}{2} = 6 \\ \dfrac{-12}{2} = -6\)

Answer 5

you divide the value of x by 2 and get y
that would be the function for your table

Answer 6

you saw for the x value you had 24
you divided that by 2 and got the y value , 12
same goes for the res

Answer 10

actually if you look at it, all you're doing is subtracting by 12

Answer 11

so to find the first ?
add 12 + (-6) = 6
second ?
-10 - 12 = -22

Answer 12

yes i got that also but what does it mean by show a function rule?

Answer 13

y = x - 12
you subtract 12 from the x value
