Answer:

The correct answer is the scatter plot which has a strong positive slope of the curve of best fit.

Step-by-step explanation:

A scatter plot shows a relationship between two variables for a particular individual. It is actually a graph where we draw a curve of best fit which can represent the whole data. A scatter plot having the correlation coefficient closest to r = 1, is said to have a very strong correlation between the variables.

A scatter plot would have a strong correlation if the data points of the individual are very close to the line or curve of best fit.

For r = 1 , the correlation is strong and positive.

Answer:

The total change that will likely occur in 2 years is $=-3\frac{2}{3}$ mg/L

Step-by-step explanation:

Given : The first year, they found the chloride concentration changed by $-1\frac{3}{5}$ mg/L .

It is estimated that the chloride concentration will change $-2\frac{1}{15}$ mg/L the next year.

To find : What is the total change that will likely occur in 2 years?

Solution :

The chloride concentration changed by $-1\frac{3}{5}=-\farc{8}{5}$ mg/L in first year.

The chloride concentration will change $-2\frac{1}{15}=-\frac{31}{15}$ mg/L the next year.

The total change that will likely occur in 2 years is

$=-\frac{8}{5}+(-\frac{31}{15})$

$=\frac{-24-31}{15}$

$=\frac{-55}{15}$

$=\frac{-11}{3}$

In a mixed fraction - $=-3\frac{2}{3}$ mg/L

I found a similar problem to your problem here, which is shown in the attached picture. So, from the picture, we have to find the equation for the red line. All we have to do is find two points of the line. That would be: Point 1(2,0) and Point 2(-2,3). The general equation would be:

y - y₁ = (y₂-y₁)/(x₂ - x₁) * (x - x₁)

Substituting the coordinates to the equation,

y - 0 = (3-0)/(-2 - 2) * (x - 2)
y = -3(x -2)/4
Rearranging,
<em>4y = -3x + 6 or 4y + 3x = 6</em>
