Answer : Graph D
Question says negative linear relationship. It means the slope is negative.
Option A and C have positive slope because the dots on graph goes up.
So we ignore A and C graph
B and D graphs have negative slope.
Given Correlation coefficient r is close to -0.5
In Graph B the dots are close to one another . It means the correlation coefficient r is close to - 1
Graph D shows a negative linear relationship with a correlation coefficient r close to =-0.5
