Question

Shannon drew the line of best fit on the scatter plot shown below:

Answer 1

What is the approximate equation of this line of best fit in slope-intercept form?

y = negative 7 over 5x + 14
y = −14x + 7 over 5
y = negative 5 over 7x + 14
y = −14x + 5 over 7

Answer 4

@raffle_snaffle

Answer 5

Take two points that go through the line and find the slope.

Answer 6

(3, 10), (5, 7)

Try these.

Answer 7

wait i dont get it is it b

Answer 8

hdudfkfb im so oooo confused

Answer 9

Slope formula:

\(\sf m = \dfrac{x_2-x_1}{y_2-y_1}\)

Plug in the points.

(3, 10), (5, 7)
x1 y1 x2 y2

Answer 10

yeah so it would be 2/3

Answer 11

Not exactly

7 - 10 = ?

Answer 12

3

Answer 13

No, check again.

Answer 14

oh sorry duh -3

Answer 15

Yes..so it's -2/3, not 2/3.

Answer 16

ohhhh so close thanks can u help me with another

Answer 17

Now plug that and one of the points into point-slope form.

Answer 18

...

Answer 19

wait im confused

Answer 20

Well, actually what's the y-intercept?

Answer 21

im so confused

Answer 22

The y-intercept is where the line crosses the y-axis.

Answer 23

yeah so whats the answer

Answer 24

Find the y-intercept.

Answer 25

What number does the line start at? At the left

Answer 26

14

Answer 27

Yes, that's the y-intercept.

Answer 28

so what does that have to do with it

Answer 29

waiiiiit is it c

Answer 30

This means that we add 14..so it can only be a or c

Answer 31

which one is it

Answer 32

Those 2 points weren't accurate, let's find the slope again using the x and y-intercepts.

(0, 14), (10, 0)
x1 y1 x2 y2

Plug them in the slope formula

Answer 33

omvkcmfkrjn jnfj fr can u just tell me the answer please

Answer 34

@rishavraj

Answer 35

No, my job is to help you, not to give you answers.

Answer 36

\(\sf \dfrac{0 - 14}{10 - 0}\)

Simplify

Answer 37

it would just equal 14/10

Answer 38

Not quite

0 - 14 = ?

Answer 39

-14

Answer 40

Yes..so it's -14/10

Now simplify that fraction.

Answer 41

bhuhbjhbuyvhbujkl

Answer 42

lol love how your green lego dude is yellow @greenlegodude57

Answer 43

i don tknow

Answer 44

-14 / 2 = ?
10 / 2 = ?
