Which associations best describe the scatter plot?

Select each correct answer.


Positive association

Linear association

Negative association

Nonlinear association

Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Time, in years. The vertical axis is labeled Number infected. Points are plotted at (one, one hundred), (two, ninety), (three, seventy-five), (four, sixty), (five, forty-five), (six, twenty-five), (seven, fifteen), (eight, five), (nine, zero).

Answer: Here you go hope this helps

If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.

Slope is = (60-70)/(25-20) = -2

Using the two-point slope form, y – y1 = m(x – x1)

               y – 70 = -2(x – 20)

               y – 70 = -2x + 40

               y = -2x + 110

Step-by-step explanation:

The associate that best describes the scatter plot is the Negative association.

What is an associate?

An associate in a scatter plot tells us the relation between the two variables. There are 4 types of associates:

Positive associate: If the value of one variable is increasing the value of another increase as well, but the relation is not linear.

Negative associate: If the value of one variable is decreasing with the value of another increasing as well, but the relation is not linear.

Linear Associate: If the value of one is dependent on the other such that they follow a function of line, and all the data points are on that function line or near to it.

Non-linear Associate: If the data points of the plot are scattered and random, such that there is no relationship between the points.

If we plot the graph of the data points we will see that the trend of the data is negative, therefore, the value of one variable is decreasing with an increase in the value of another.

Hence, the associate that best describes the scatter plot is the Negative association.
