What is the slope of this line of best fit?

Bas_tet [7]

Answer:

The slope of the line of best fit is $\frac{-6}{7}$ ⇒ 2nd option

Step-by-step explanation:

The formula of the slope of a line is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

<em>To find the slope of the best line fit choose two points their positions make the number of the points over the line equal to the number of the points below the line</em>

From the attached graph points (1 , 9) and (8 , 3) are the best choice

∵ The line passes through points (1 , 9) and (8 , 3)

∴ $x_{1}$ = 1 and $x_{2}$ = 8

∴ $y_{1}$ = 9 and $y_{2}$ = 3

- Substitute them in the formula of the slope

∴ $m=\frac{3-9}{8-1}=\frac{-6}{7}$

∴ The slope of the line of best fit is $\frac{-6}{7}$

I’m really confused somebody please help

Nady [450]

Answer: The mechanic worked for 4.25 hours for the fourth customer.

First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60

Slope: 60

Then find out what the y-intercept is by plugging in values we know into y=mx+b

90=60(1)+b
30=b

Y=60x+30

Substitute the y with 285 to find out the x (hours)

285=60x+30
4.25=x

Write an expression for the sum of four consecutive odd integers where 2n +1 represents the smallest odd integer.

7nadin3 [17]

8n+16
the four odd numbers are 2n+1, 2n+3, 2n+5, 2n+7
2n+1+2n+3+2n+5+2n+7=8n+16
