Question

Based on the scatter plot below, which is a better prediction for x when y=3?
A.0
B.8

Answer 1

So look at y= 3

What are the x values given on the graph

Answer 2

0,2,4,6,8,10

Answer 3

That's from the x-axis

I'm talking about the points

Which points are there where the y-value is 3

Answer 4

Remember points are labeled like (x, y)

Y is the vertical one and x is the horizontal one

Answer 5

oh, okay. It looks like there both labeled like that

Answer 6

You're looking at the bottom lines and not the points



Here's an example, you see how that dot

It's where x (the horizontal) = 4 and y (the vertical) = 4

So the point is labelled (x, y) which would be (4, 4)

Do you understand?

Answer 7

yes

Answer 8

so by this am I supposed to look at which answer is close or y-axis is 3?

Answer 9

Similarly this is how (2, 3) would be

Answer 10

So yes, so on the vertical line, go up to 3

And then slide your finger across horizontally this way --->

What points do you see

Answer 11

I see some points close to 8 but no (8,3) or (0,3)

Answer 12

yes, so we're not trying to find an exact point but rather where another point could be in the graph

So you can see the points follow a pattern

Answer 13

See how as the x-value increases, the y-value on average is decreasing

Answer 14

So the question you have is asking

Which of the two points belongs on this graph. Which one fits in?

Is it (0, 3) or (0, 8)

Answer 15

(0, 3) or (8, 3) *****

Answer 16

(8,3)

Answer 17

And that's right!!

(0, 8) would also be right if the question was more in general and not asking about y=3

But good job!!

Answer 18

Thank you so much!

Answer 19

It was my pleasure!
