Question

A researcher justified the following conclusion with a scatter plot and a line of best fit.

As the number of siblings a student has increases, the student's score on a standardized test decreases.

Let x represent the number of siblings and y represent the standardized test score. Based on the conclusion above, which of these could be the equation of the line of best fit for the researcher's data?

Answer 1

Can anyone tell me an equation to represent this

Answer 2

we know that it would look like an X

Answer 3

or rather a /

Answer 4

those are the choices

Answer 5

i can't open those tabs

Answer 6

ohh hold on

Answer 7

There you go :)

Answer 8

first one makes no sense, why would you start with 50 siblings?

Answer 9

You don't it is a multiple choice they always put ridiculous choices lol

Answer 10

the only one I see that would come close to making sense would be the last one ( I MAY BE WRONG) I am not sure how to solve this one. do you have an example?

Answer 11

That is why I asked you I was really confused

Answer 12

would it be third one because the the number of a student increases it shows the test score decreasing but maybe not

Answer 13

I can't really help you with this one @mathslover cam help us?
