Which two points should the line of best fit go through to best represent the data in the scatterplot?

Ilya [14]

Given : A graph with points (1, 3), (2, 7), (3, 8), (4, 11), (5, 12), (6, 13).

To find : From Which two points the line of best fit goes through

Solution:

(3, 8) & (5, 12) will be two points

as then line points will be

( 1 , 4 ) , ( 2, 6) , ( 3 , 8 ) , ( 4, 10) , (5 . 12) & ( 6 , 14)

(1, 3) will be below ( 1 , 4 )

(2 , 7) will be above ( 2 , 6)

( 3 , 8 ) will be on line

(4 , 11 ) will be above ( 4 , 10)

( 5 , 12 ) will be on line

( 6 , 13) will be below ( 6 , 14 )

(1, 3) & ( 6 , 13) two points are below line

(2 , 7) & (4 , 11 ) two points above line

Hence points are Equally scattered above & below line

Hence (3, 8) & (5, 12) will be two points on line of best fit

Hope it helpss !!

3x+10y=13<br> 4(-2y+x)-9x=13

mart [117]

Answer:

$x=-9$

$y=4$

Step-by-step explanation:

$3x+10y=13$ ← Equation 1

$4(-2y+x)-9x=13\\$

By simplifying the above equation we get,

$-8y+=4x-9x=13$ (Simplifying the brackets)

$-8y-5x=13$ (By subtracting $-9x$ from $+4x$ ) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

$15x+50y=65$

Equation 2 multiplied by 3 will give,

$-24y-15x=39$

Add those together,

$15x+50y-24y-15x=65+39$

$26y=104$ (After simplifying $x$ values)

Therefor $y=4$

By substituting $y=4$ to Equation 1 we get,

$3x+10*4=13$ $3x+40=13\\3x=-27\\x=-9$

Therefor we can say,

$x=-9$

$y=4$
