4 : 28 is the same as 4/28
4/28 = 1/7
The answer is C
The only true statement is A:
"The data show a negative linear relationship."
<h3>
</h3><h3>
Which statement is true?</h3>
On the graph, we can see how the car's vale decreases almost linearly with the age of the car.
Where the response variable would be the one on the y-axis, which is the car's value.
For that linear behavior, we know that there is a correlation coefficient different than zero. So options B, C, and D are false.
Finally, we already saw the linear behavior (decreasing, so the slope is negative). Then we conclude that the only true statement is A.
