Use the image to answer the question. A scatterplot shows the number of hours studied versus test grade. The horizontal axis shows the number of hours studied, ranging from 0 to 10 in increments of 1. The vertical axis shows the test grade, ranging from 0 to 100 in increments of 5, starting with a jump from 0 to 35. A kink is shown on the vertical axis close to origin. A dot is plotted at 0.5 on the horizontal axis and 45 on the vertical axis. A loosely packed cluster of data plots is plotted between 1 to 4.5 on the horizontal axis and 77 and 98 on the vertical axis. What are the characteristics of the graph?

The scatterplot shows a positive correlation between the number of hours studied and test grade. As the number of hours studied increases, the test grade tends to increase as well. The kink on the vertical axis close to the origin may indicate a minimum passing grade. The data points are tightly clustered between 1 to 4.5 on the horizontal axis and show high test grades ranging from 77 to 98, suggesting that students who study between 1 to 4.5 hours tend to score well on the test. The dot plotted at 0.5 on the horizontal axis and 45 on the vertical axis may represent an outlier where a student scored low on the test despite studying for a short amount of time.
