Question

Graphing Operations

Answer 1

1 :) do you want me to explain this one?

Answer 2

ya if you dont mind

Answer 3

i would love to learn

Answer 4

haha ok :)
Look at the equation 3x+2=y ; y=5
the equation says that y=5 so you plug it into the y spot giving you:
3x+2=5

Answer 5

ok i understand that

Answer 6

now make a function :) do you know how to do that?

Answer 7

i was watching you explain it and taking notes

Answer 8

Ok, great :) so, we start at the first equation and ignore the fact that it says "y=5" giving us 3x+2=y and we write

Answer 9

all this means is that if x=1 y has to equal 5 or if y=5 then x has to equal 1 :) and if x=2 then y=8 and so on and so forth, do you see how to do it now?

Answer 10

oh ok so its basically multiplying

Answer 11

kind of... let's pick up where we left off :) 3x+2=5 ... now we subtract 2 on both sides of the equation giving us 3x=3

Answer 12

so it gave me the answer of 3

Answer 13

nope now we do this...\[\frac{ 3x }{ 3 }=3\]

Answer 14

the 3's on the left side

Answer 15

cancel out and the three on the left becomes 1 because 3 divided by 3 is 1 :)

Answer 16

\[\frac{ 3x }{ 3 }= \frac{ 3 }{ 3 }\]

Answer 17

u r very good at this

Answer 18

haha I guess :) I used to be very confused when it came to this then I just practiced and started to get the hang of it. :) this is my second year in algebra :)

Answer 19

but I guess it helps when you think math is fun lol :)

Answer 20

lol ya or if youre just awesome like u

Answer 21

oh wait so its 1

Answer 22

haha yes it is 1 :) so to sum it up all we did was substitute y in for 5 giving us 3x+2=5 and then we think what times 3 gives us a number that can be added to 2 and give us 5.

Answer 23

does that make it easier to understand? :)
