Answer 1

So what do you know about the graph?

Answer 2

I don't really understand what you mean. The graph show in the link.

Answer 3

I know, but since it's your problem I want you to think about it. That's how you're going to learn how to do this in the future.

Answer 4

oh, thanks.. I guess the original is y= -1/3x, and the height will be 4??
so F(x,y)=y+1/3*x... that is all i can think of right now

Answer 5

the height keeps changing, so you need to have a variable for it.

Answer 6

so you're right about the first park. y=-1/3x
But y already means something, so you want to choose a different variable for the y-intercept.

Answer 7

I am sorry, i dont really get it.

Answer 8

okay, well do you understand why y=-1/3x, since you came up with that?

Answer 9

yes, get the first line and the original. and we can see the slope is -1/3

Answer 10

Oh my god, the text kept resended

Answer 11

Don't worry. It's just on your computer. I have that happen a lot.

okay, and you now that there are a lot of lines with the same slope, right?

Answer 12

yes, and they are paralleled equa spaced

Answer 13

right

and you know that the slope intercept form of an equation for a line is y=mx+b

Answer 14

so you know what m is, so now you need to figure out what b is.

Answer 15

i think about 4/3*t

Answer 16

That looks about right to me.

Answer 17

I am a lil bit confused. Why they give the value on the y=x

Answer 18

what?

Answer 19

they spaced it out from 14- -6, what r those number for?

Answer 20

I think those are the values of t

Answer 21

plse help
