Answer:
The first graph (topmost graph)
Explanation:
Correlation coefficient of -1: Negative correlation
As variable x (horizontal axis) increases, variable y (vertical axis) should decrease.
Hence, gradient of the graph is negative, sloping downwards as x increases.
Graph 2 is eliminated (positive correlation approximately 1)
Graph 4 is also wrong as there is simply no correlation. (Points are random with no fixed pattern or trend)
Graphs 1 and 3 show negative correlation.
However, for graph 3, several points are not accurate, leading to a straight line not being drawn accurately. (Slightly off) . Correlation of this graph is negative but not closest to -1.
Hence, the first graph is the closest to -1 in terms of correlation coefficient.
