Question

Naomi plotted the graph below to show the relationship between the temperature of her city and the number of popsicles she sold daily:
Part A: In your own words, describe the relationship between the temperature of the city and the number of popsicles sold. (2 points)
Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept. (3 points)

i got a done but not b

Answer 1

heres the right one

Answer 2

@pooja195 heres the right one

Answer 3

:,(

Answer 4

i dont understant it at all

Answer 5

at least b i got a done

Answer 6

so hmmm are you doing part B onlyl you said? you already did part A?

Answer 7

yes

Answer 8

hmmm you know what a "best fit line" is, right?

and how to get the slope of a line, right?

Answer 9

a line that goes in the middle of all the plots right

Answer 10

or at least the one that is the closest to the middle

Answer 11

well, a LINE that represents or mimicks the relationship of both items
bearing in mind that, their relationship may have scattered points, not in-a-line

Answer 12

ok

Answer 13

well, since when it's hot, you'd want to eat something really cold, and the hotter, the colder is better, or more of it

then I'd say, neverminding all points no in the line, you could simply a slanted line
like so, check pic

Answer 14

ok

Answer 15

now to get the slope of that line, easy, pick two points IN the line
and get their slope
let's say hmmm 10 popsicles when the temperature is 40F, so 40,10
and say 20 popsicles when it's 90F, thus 90,20

then \(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({\color{red}{ 40}}\quad ,&{\color{blue}{ 10}})\quad
% (c,d)
&({\color{red}{ 90}}\quad ,&{\color{blue}{ 20}})
\end{array}
\\\quad \\
% slope = m
slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies
\cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)

Answer 16

THANKS!!!!!
