Based on the description of the line in the coordinate plane that moves diagonally upward from left to right, the best statement to describe the data illustrated in the graph is:
The graph illustrates a strong positive correlation between the data.
This is because an upward slope indicates that as one variable increases, the other variable also tends to increase, which defines a positive correlation. Since there are 25 closed points plotted along the line (including points above, below, and on the line), it suggests a strong relationship that is still primarily positive.
