graph the line of best fit.
click to plot a point. two points plot a line.
click a plotted point to delete it.
Step1: Identify the trend
The scatter plot shows a negative correlation (as x increases, y decreases). We need to find two points that roughly balance the number of points above and below the line.
Step2: Estimate key points
Looking at the distribution, we can estimate two points. For example, a point in the upper - left cluster and a point in the lower - right cluster. Let's assume we pick a point with a relatively high y - value and low x - value, and a point with a relatively low y - value and high x - value. After estimating, we can plot these two points and draw a line through them. (Since this is a graphical task, the main idea is to find the line that best represents the trend of the data points, minimizing the overall distance from the points to the line.)

To graph the line of best fit:
- Observe the general trend of the scatter plot (negative correlation here, as \(x\) increases, \(y\) decreases).
- Identify two points that seem to be representative of the central tendency of the data. For example, pick a point from the upper - left group of points and a point from the lower - right group of points.
- Plot these two points and draw a straight line through them. The line should be positioned such that it is as close as possible to all the data points, with a roughly equal number of points above and below the line. (Note: Since this is a visual/graphical task, the exact points will depend on the visual estimation of the scatter plot's trend.)
