The tables below show four sets of data:

set a
x 1 2 3 4 5 6 7 8 9
y 10 9 8 7 6 5 4 3 2
set b
x 1 2 3 4 5 6 7 8 9
y 3 4 5 6 7 8 9 10 11

set c
x 1 2 3 4 5 6 7 8 9
y 8 6 5 4 3.5 3 2.5 2 2
set d
x 1 2 3 4 5 6 7 8 9
y 1 2.5 2.5 3 4 5 6 8 9

for which set of data will the scatter plot represent a negative linear association between x and y? (4 points)

set a
set b
set c
set d

Hence, the set that represent a negative linear association between x and y is:

Set A.

Step-by-step explanation:

We are given 4 sets of data as:

Set A  

x123456789  

y1098765432

Set B  

x123456789  

y34567891011

Set C  

x123456789  

y86543.532.522

Set D  

x123456789  

y12.52.5345689

We are asked to determine the set which represent negative linear association between x and y?

         y=11-x or y= -x+11.

Hence, clearly we could see that the relationship is linear and also negative as the value of y keeps on decreasing with increasing x.

Hence, the set that represent a negative linear association between x and y is:

Set A.

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
