The line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025

<h3>What is the line of best fit?</h3>

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

We have data shown in the table:

To find the line of best fit, we will calculate its slope and y-intercept.

We know the slope is given by:

\rm m = \dfrac{n\sum xy-\sum x \sum y}{n \sum x^2 - (\sum x)^2}   where n = 5

After calculating, we get,

\rm n\sum xy-\sum x \sum y = 105000  and

\rm n \sum x^2 - (\sum x)^2 = 50

m = 105000/50 = 2100

For y-intercept b:

\rm b = \dfrac{\sum y -m \sum x}{n}

After calculating:

b = -4166040

The line becomes:

y = 2100x -4166040

If x = 2025 put this value in the line, we get:

y = 86460

Thus, the line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025

Determine whether each equation represents a linear or non linear function, help me plzz
Ksju [112]

Answer:

y=3x - Linear Function

y=4x-1 - Linear Function

y=x²+1 - Non-Linear Function

y=0.75x+2 - Linear Function

y=0.5x³ - Non-Linear Function

(For a function to be linear, both x & y must equal 1.)

Answer:

(3, 3)

Step-by-step explanation:

do you need to show your work or just the answer?

-3x+7y=12                                   mulitply both sides by 3 of the bottom.

x-2y=-3

-3x+7y=12                    

3x-6y=-9           < which turns into this

Then you have to sum the equations (vertically) to eliminate one variable.

y=3

Then substitute the given value of "y" into the equation

x-2 * 3=-3    then solve the equation for x      (x=3)

y=3   x=3    (3, 3)

*Check your answers.

-3*3+7*3=12

3-2*3=-3

12=12

-3=-3

(-3, -3)
