which one is a linear association?
option 1
x: 5 8 2 4 6 12 10 1 3 7
y: 550 800 350 450 700 1000 900 250 400 750
option 2:
x: 5 8 2 4 6 12 10 1 3 7
y:800 700 350 450 500 1000 900 250 400 750
option 3:
x: 5 8 2 4 6 12 10 1 3 7
y:550 800 250 300 700 1000 650 300 100 700
option 4:
x: 5 8 2 4 6 12 10 1 3 7
y: 550 800 250 500 500 400 650 150 400 750
Option 2 appears to have a linear association between x and y because the values of y change consistently as x increases.
are you sure
My apologies for any confusion in my previous response. After reviewing the options again, it looks like none of the given options have a clear linear association between x and y. The values of y do not consistently increase or decrease in a linear pattern as x changes. Therefore, none of the options have a linear association.
To determine which option represents a linear association, we need to examine the relationship between the two variables, x and y, for each option.
In a linear association, the relationship between x and y can be described by a straight line. This means that as x increases, y also increases or decreases by a constant rate.
Option 1:
x: 5 8 2 4 6 12 10 1 3 7
y: 550 800 350 450 700 1000 900 250 400 750
Option 2:
x: 5 8 2 4 6 12 10 1 3 7
y: 800 700 350 450 500 1000 900 250 400 750
Option 3:
x: 5 8 2 4 6 12 10 1 3 7
y: 550 800 250 300 700 1000 650 300 100 700
Option 4:
x: 5 8 2 4 6 12 10 1 3 7
y: 550 800 250 500 500 400 650 150 400 750
To determine if there is a linear association, we can create a scatter plot of the data points and observe if they form a straight line.
After plotting the data points for each option, we can see that only Option 2 represents a linear association. The points in Option 2 create a line that moves downwards from left to right, showing a negative slope. This indicates a linear relationship between x and y.
Therefore, Option 2 is the correct answer as it represents a linear association.
