Question

Part A: What is the approximate y-intercept of the line of best fit and what does it represent?

Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice.

Answer 1

help

Answer 2

I will fan and medal the first response and the answer with explanation

Answer 3

First off we have to find the slope of the line.

Answer 4

so rise over run so 2 over 1

Answer 5

Answer 6

@SyedMohammed98

Answer 7

what is the next step

Answer 8

its fine : (

Answer 9

if you know anybody on open study who can could you tag them

Answer 10

Answer 11

@Kitten_is_back

Answer 12

okay :D

Answer 13

or if you can help that be great to

Answer 14

have you try to slove it love?

Answer 15

yesish

Answer 16

I think the y intercept is 3

Answer 17

okay can you show me what you have so far?

Answer 18

okay why do you think its 3?

Answer 19

well because based off of the line of best fit it looks like if it continued it would be 3

Answer 20

so what do I do now

Answer 21

somebody help I just need help on this last home work question and I'll be done

Answer 22

so I'm correct on the y-intercept

Answer 23

the y -intercept is 3, it shows the point (0,3) . It means: with 0 months of practice, the opportunity to win the matches is 3.

Answer 24

Ok so now to find the equation we need the slope and y-intercept but the points there is no association

Answer 25

for B) you have one point (0,3) , pick another point to write down the equation line. To me, I like point(5,12) .

Answer 26

I lost the net so that I can't guide you more.
the equation of the line passes through those points is y = (9/5) x +3

Answer 27

sorry my computers acting up

Answer 28

with x is the months of practice, you replace x =13 to find y , that is the answer for b

@doresmith

Answer 31

what do you need help with..?

Answer 32

b I still don't get it

Answer 33

ok... so you know the y- intercept is y = 3 or the point (0,3)

have you found the slope of the line..?

Answer 34

no because thats what I don't get how to find it with all the points being scattered

Answer 35

and having it be accurate

Answer 36

well pick points on the line

(0,3)seems to be on the line and so does (5, 12)

can you find the slope between these 2 points..?

Answer 37

would it be 2.4

Answer 38

for (5,12)

Answer 39

@campbell_st

Answer 40

well (12 -3)/(5 - 0) = 9/5 or 1.8

Answer 41

why are you subtracting

Answer 42

you now know the y- intercept and slope

so you can find the equation of the line

y = mx + b m = slope and b = y-intercept

Answer 43

So it be y=1.8x+3

Answer 44

thats the formula for the slope of the line

change in y divided by change in x

using the points (5, 12) and (0,3)

the change in y in 12 - 3 = 9

the change in x is 5 - 0 = 5

the slope is 9/5 or 1.8

Answer 45

Thank You I can figure the rest out

Answer 46

that's correct for the equation.

last task is to substitute x = 13 and calculate the answer.

that will be the number of games won after 13 months of practice
